5.1. NK Cells

[0094] Described herein are NK cells, including PiNK cells, activated NK cells, TSPNK cells, and NK cells produced by the three-stage method.

5.1.1. Placental Intermediate Natural Killer (PiNK) Cells

[0095] In some embodiments, natural killer cells are placental intermediate natural killer (PiNK) cells (see also U.S. Pat. No. 8,263,065, the disclosure of which is hereby incorporated by reference in its entirety). In various embodiments, PiNK cells are derived from placental cells. In specific embodiments, the placental cells are obtained from placental perfusate, e.g., human placental perfusate. In specific embodiments, the placental cells are obtained from placental tissue that has been mechanically and/or enzymatically disrupted.

[0096] PiNK cells are characterized as being CD56.sup.+CD16.sup., i.e., displaying the CD56 cellular marker and lacking the CD16 cellular marker, e.g., as determined by flow cytometry, e.g., fluorescence-activated cell sorting using antibodies against CD16 and CD56, as described above.

[0097] In certain embodiments, the PiNK cells are CD3.sup..

[0098] In other embodiments, the PiNK cells do not exhibit one or more cellular markers exhibited by fully mature natural killer cells (e.g., CD16), or exhibit such one or more markers at a detectably reduced level compared to fully mature natural killer cells, or exhibit one or more cellular markers associated with natural killer cell precursors but not fully mature natural killer cells. In a specific embodiment, a PiNK cell described herein expresses NKG2D, CD94 and/or NKp46 at a detectably lower level than a fully mature NK cell. In another specific embodiment, a plurality of PiNK cells described herein expresses, in total, NKG2D, CD94 and/or NKp46 at a detectably lower level than an equivalent number of fully mature NK cells.

[0099] In certain embodiments, PiNK cells express one or more of the microRNAs hsa-miR-100, hsa-miR-127, hsa-miR-211, hsa-miR-302c, hsa-miR-326, hsa-miR-337, hsa-miR-497, hsa-miR-512-3p, hsa-miR-515-5p, hsa-miR-517b, hsa-miR-517c, hsa-miR-518a, hsa-miR-518e, hsa-miR-519d, hsa-miR-520g, hsa-miR-520 h, hsa-miR-564, hsa-miR-566, hsa-miR-618, and/or hsa-miR-99a at a detectably higher level than peripheral blood natural killer cells.

[0100] Because the post-partum placenta comprises tissue and cells from the fetus and from the mother placental perfusate, depending upon the method of collection, PiNK cells can comprise fetal cells only, or a substantial majority of fetal cells (e.g., greater than about 90%, 95%, 98% or 99%), or can comprise a mixture of fetal and maternal cells (e.g., the fetal cells comprise less than about 90%, 80%, 70%, 60%, or 50% of the total nucleated cells of the perfusate). In one embodiment, the PiNK cells are derived only from fetal placental cells, e.g., cells obtained from closed-circuit perfusion of the placenta (see above) wherein the perfusion produces perfusate comprising a substantial majority, or only, fetal placental cells. In another embodiment, the PiNK cells are derived from fetal and maternal cells, e.g., cells obtained by perfusion by the pan method (see above), wherein the perfusion produced perfusate comprising a mix of fetal and maternal placental cells. Thus, in one embodiment, the NK cells are a population of placenta-derived intermediate natural killer cells, the substantial majority of which have the fetal genotype. In another embodiment, the NK cells are a population of placenta-derived intermediate natural killer cells that comprise natural killer cells having the fetal genotype and natural killer cells having the maternal phenotype.

5.1.2. Activated NK Cells

[0101] In some embodiments, natural killer cells are activated NK cells (i.e., Two-Step NK cells, or TSNK cells) (see also U. S. Patent Application Publication No. 2012/0148553, the disclosure of which is hereby incorporated by reference in its entirety), which are NK cells produced by any method/process described below in Section 5.2.4.

[0102] In a specific embodiment, the activated NK cells are CD3.sup.CD56.sup.+. In a specific embodiment, the activated NK cells are CD3.sup.CD56.sup.+CD16.sup.. In another specific embodiment, the activated NK cells are additionally CD94.sup.+CD117.sup.+. In another specific embodiment, the activated NK cells are additionally CD161.sup.. In another specific embodiment, the activated NK cells are additionally NKG2D.sup.+. In another specific embodiment, the activated NK cells are additionally NKp46.sup.+. In another specific embodiment, the activated NK cells are additionally CD226.sup.+.

[0103] In certain embodiments, greater than 50%, 60%, 70%, 80%, 90%, 92%, 94%, 96%, 98% of said activated NK cells are CD56.sup.+ and CD16.sup.. In other embodiments, at least 50%, 60%, 70%, 80%, 82%, 84%, 86%, 88% or 90% of said activated NK cells are CD3.sup. and CD56.sup.+. In other embodiments, at least 50%, 52%, 54%, 56%, 58% or 60% of said activated NK cells are NKG2D.sup.+. In other embodiments, fewer than 30%, 20%, 10%, 9%, 8%, 7%, 6%, 5%, 4% or 3% of said cells are NKB1.sup.+. In certain other embodiments, fewer than 30%, 20%, 10%, 8%, 6%, 4% or 2% of said activated NK cells are NKAT2.sup.+. In certain other embodiments, fewer than 30%, 20%, 10%, 8%, 6%, 4% or 2% of said activated NK cells are CD56.sup.+ and CD16.sup.+. In more specific embodiments, at least 10%, 20%, 25%, 30%, 35%, 40%, 50%, 55%, 60%, 65% or 70% of said CD3.sup., CD56.sup.+ activated NK cells are NKp46.sup.+. In other more specific embodiments, at least 10%, 20%, 25%, 30%, 35%, 40%, 50%, 55%, 60%, 65%, 70%, 75%, 80% or 85% of said CD3.sup., CD56.sup.+ activated NK cells are CD117.sup.+. In other more specific embodiments, at least 10%, 20%, 25%, 30%, 35%, 40%, 45% or 50% of said CD3.sup., CD56.sup.+ activated NK cells are CD94.sup.+. In other more specific embodiments, at least 10%, 20%, 25%, 30%, 35%, 40%, 45% or 50% of said CD3.sup., CD56.sup.+ activated NK cells are CD161.sup.. In other more specific embodiments, at least 10%, 12%, 14%, 16%, 18% or 20% of said CD3.sup., CD56.sup.+ activated NK cells are CD226.sup.+. In more specific embodiments, at least 20%, 25%, 30%, 35% or 40% of said CD3.sup., CD56.sup.+ activated NK cells are CD7.sup.+. In more specific embodiments, at least 30%, 35%, 40%, 45%, 50%, 55% or 60% of said CD3.sup., CD56.sup.+ activated NK cells are CD5.sup.+.

[0104] Activated NK cells can have a fetal genotype or a maternal genotype. For example, because the post-partum placenta, as a source of hematopoietic cells suitable for producing activated NK cells, comprises tissue and cells from the fetus and from the mother, placental perfusate can comprise fetal cells only, or a substantial majority of fetal cells (e.g., greater than about 90%, 95%, 98% or 99%), or can comprise a mixture of fetal and maternal cells (e.g., the fetal cells comprise less than about 90%, 80%, 70%, 60%, or 50% of the total nucleated cells of the perfusate). In one embodiment, the activated NK cells are derived only from fetal placental hematopoietic cells, e.g., cells obtained from closed-circuit perfusion of the placenta wherein the perfusion produces perfusate comprising a substantial majority, or only, fetal placental hematopoietic cells. In another embodiment, the activated NK cells are derived from fetal and maternal cells, e.g., cells obtained by perfusion by the pan method (see above), wherein the perfusion produced perfusate comprising a mix of fetal and maternal placental cells. Thus, in one embodiment, the activated NK cells are derived from a population of placenta-derived intermediate natural killer cells, the substantial majority of which have the fetal genotype. In another embodiment, the activated NK cells are derived from a population of placenta-derived intermediate natural killer cells that comprise natural killer cells having the fetal genotype and natural killer cells having the maternal phenotype.

[0105] In certain embodiments, the activated NK cells or populations enriched for activated NK cells can be assessed by detecting one or more functionally relevant markers, for example, CD94, CD161, NKp44, DNAM-1, 2B4, NKp46, CD94, KIR, and the NKG2 family of activating receptors (e.g., NKG2D).

[0106] Optionally, the cytotoxic activity of isolated or enriched natural killer cells can be assessed, e.g., in a cytotoxicity assay using tumor cells, e.g., cultured K562, LN-18, U937, WERI-RB-1, U-118MG, HT-29, HCC2218, KG-1, or U266 tumor cells, or the like as target cells.

5.1.3. Three-Step Process NK (TSPNK) Cells

[0107] In some embodiments, natural killer cells are Three-Step Process NK (TSPNK) cells, which are NK cells produced by any method/process described below in Section 5.2.5. In specific embodiments, the TSPNK cells are NK progenitor cells (see also U. S. Patent Application Publication No. 2012/0148553, the disclosure of which is hereby incorporated by reference in its entirety).

The relative numbers of cells from each source can be selected based on, e.g., the number of one or more specific cell types in the cells to be pooled, e.g., the number of CD34.sup.+ cells, etc.

[0142] NK cells produced using the processes described herein, e.g., activated NK cells or TSPNK cells (e.g., NK progenitor cells), and combinations of such cells with placental perfusate and/or placental perfusate cells can be assayed to determine the degree or amount of tumor/infection suppression (that is, the potency) to be expected from, e.g., a given number of the NK cells, or a given volume of perfusate. For example, an aliquot or sample number of cells is contacted or brought into proximity with a known number of tumor/infected cells under conditions in which the tumor/infected cells would otherwise proliferate, and the rate of proliferation of the tumor/infected cells in the presence of placental perfusate, perfusate cells, placental natural killer cells, or combinations thereof, over time (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 weeks, or longer) is compared to the proliferation of an equivalent number of the tumor/infected cells in the absence of perfusate, perfusate cells, placental natural killer cells, or combinations thereof. The potency of the cells can be expressed, e.g., as the number of cells or volume of solution required to suppress tumor cell growth/infection spread, e.g., by about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or the like.

Matched units, as used herein, indicates that the NK cells are obtained from placental perfusate cells, and umbilical cord blood cells, wherein the umbilical cord blood cells are obtained from umbilical cord blood from the placenta from which the placental perfusate is obtained, i.e., the placental perfusate cells and umbilical cord blood cells, and thus the natural killer cells from each, are from the same individual.

[0147] In certain embodiments, the combined placental killer cells comprise only, or substantially only, natural killer cells that are CD56.sup.+ and CD16.sup.. In certain other embodiments, the combined placental killer cells comprise NK cells that are CD56.sup.+ and CD16.sup., and NK cells that are CD56.sup.+ and CD16.sup.+.

5.1.5.3. Combinations of NK Cells with Adherent Placental Stem Cells

[0152] In other embodiments, the NK cells produced using the processes described herein, e.g., activated NK cells or TSPNK cells (e.g., NK progenitor cells) produced using the three-step process described herein, either alone or in combination with placental perfusate or placental perfusate cells, are supplemented with isolated adherent placental cells, e.g., placental stem cells and placental multipotent cells as described, e.g., in Hariri U.S. Pat. Nos. 7,045,148 and 7,255,879, and in U.S. Patent Application Publication No. 2007/0275362, the disclosures of which are incorporated herein by reference in their entireties. Adherent placental cells means that the cells are adherent to a tissue culture surface, e.g., tissue culture plastic. The adherent placental cells useful in the compositions and methods disclosed herein are not trophoblasts, embryonic germ cells or embryonic stem cells. In certain embodiments, adherent placental stem cells are used as feeder cells during the processes (e.g., two-step method) as described above.

[0153] The NK cells produced using the processes described herein, e.g., activated NK cells or TSPNK cells (e.g., NK progenitor cells), either alone or in combination with placental perfusate or placental perfusate cells can be supplemented with, e.g., 110.sup.4, 510.sup.4, 110.sup.5, 510.sup.5, 110.sup.6, 510.sup.6, 110.sup.7, 510.sup.7, 110.sup.8, 510.sup.8 or more adherent placental cells per milliliter, or 110.sup.4, 510.sup.4, 110.sup.5, 510.sup.5, 110.sup.6, 510.sup.6, 110.sup.7, 510.sup.7, 110.sup.8, 510.sup.8, 110.sup.9, 510.sup.9, 110.sup.10, 510.sup.10, 110.sup.11 or more adherent placental cells. The adherent placental cells in the combinations can be, e.g., adherent placental cells that have been cultured for, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, or 40 population doublings, or more.

[0154] Isolated adherent placental cells, when cultured in primary cultures or expanded in cell culture, adhere to the tissue culture substrate, e.g., tissue culture container surface (e.g., tissue culture plastic). Adherent placental cells in culture assume a generally fibroblastoid, stellate appearance, with a number of cytoplasmic processes extending from the central cell body. Adherent placental cells are, however, morphologically distinguishable from fibroblasts cultured under the same conditions, as the adherent placental cells exhibit a greater number of such processes than do fibroblasts. Morphologically, adherent placental cells are also distinguishable from hematopoietic stem cells, which generally assume a more rounded, or cobblestone, morphology in culture.

[0155] The isolated adherent placental cells, and populations of adherent placental cells, useful in the compositions and methods provided herein, express a plurality of markers that can be used to identify and/or isolate the cells, or populations of cells that comprise the adherent placental cells. The adherent placental cells, and adherent placental cell populations useful in the compositions and methods provided herein include adherent placental cells and adherent placental cell-containing cell populations obtained directly from the placenta, or any part thereof (e.g., amnion, chorion, amnion-chorion plate, placental cotyledons, umbilical cord, and the like). The adherent placental stem cell population, in one embodiment, is a population (that is, two or more) of adherent placental stem cells in culture, e.g., a population in a container, e.g., a bag.

[0156] The adherent placental cells generally express the markers CD73, CD105, and CD200, and/or OCT-4, and do not express CD34, CD38, or CD45. Adherent placental stem cells can also express HLA-ABC (MHC-1) and HLA-DR. These markers can be used to identify adherent placental cells, and to distinguish the adherent placental cells from other cell types. Because the adherent placental cells can express CD73 and CD105, they can have mesenchymal stem cell-like characteristics. Lack of expression of CD34, CD38 and/or CD45 identifies the adherent placental stem cells as non-hematopoietic stem cells.

[0157] In certain embodiments, the isolated adherent placental cells described herein detectably suppress cancer cell proliferation or tumor growth.

5.2. Methods of Producing NK Cells

[0174] NK cells may be produced from hematopoietic cells, e.g., hematopoietic stem or progenitors from any source, e.g., placental tissue, placental perfusate, umbilical cord blood, placental blood, peripheral blood, spleen, liver, or the like.

[0175] One important source of natural killer cells and cells that can be used to derive natural killer cells as described above is the placenta, for example, full-term placenta, e.g., full-term human placenta. Placental perfusate comprising placental perfusate cells that can be obtained, for example, by the methods disclosed in U.S. Pat. Nos. 7,045,148 and 7,468,276 and U.S. Patent Application Publication No. 2009/0104164, the disclosures of each of which are hereby incorporated in their entireties.

Perfusate can be collected from the placenta by perfusion of the placenta with any physiologically-acceptable solution, e.g., a saline solution, culture medium, or a more complex cell collection composition. A cell collection composition suitable for perfusing a placenta, and for the collection and preservation of perfusate cells is described in detail in related U.S. Application Publication No. 2007/0190042, which is incorporated herein by reference in its entirety.

Such components can be, e.g., an apoptosis inhibitor (e.g., a caspase inhibitor or JNK inhibitor); a vasodilator (e.g., magnesium sulfate, an antihypertensive drug, atrial natriuretic peptide (ANP), adrenocorticotropin, corticotropin-releasing hormone, sodium nitroprusside, hydralazine, adenosine triphosphate, adenosine, indomethacin or magnesium sulfate, a phosphodiesterase inhibitor, etc.); a necrosis inhibitor (e.g., 2-(1H-Indol-3-yl)-3-pentylamino-maleimide, pyrrolidine dithiocarbamate, or clonazepam); a TNF- inhibitor; and/or an oxygen-carrying perfluorocarbon (e.g., perfluorooctyl bromide, perfluorodecyl bromide, etc.).

[0179] The cell collection composition can comprise one or more tissue-degrading enzymes, e.g., a metalloprotease, a serine protease, a neutral protease, a hyaluronidase, an RNase, or a DNase, or the like. Such enzymes include, but are not limited to, collagenases (e.g., collagenase I, II, III or IV, a collagenase from Clostridium histolyticum, etc.); dispase, thermolysin, elastase, trypsin, LIBERASE, hyaluronidase, and the like.

[0181] The cell collection composition can also comprise one or more of the following compounds: adenosine (about 1 mM to about 50 mM); D-glucose (about 20 mM to about 100 mM); magnesium ions (about 1 mM to about 50 mM); a macromolecule of molecular weight greater than 20,000 daltons, in one embodiment, present in an amount sufficient to maintain endothelial integrity and cellular viability (e.g., a synthetic or naturally occurring colloid, a polysaccharide such as dextran or a polyethylene glycol present at about 25 g/l to about 100 g/l, or about 40 g/l to about 60 g/l); an antioxidant (e.g., butylated hydroxyanisole, butylated hydroxytoluene, glutathione, vitamin C or vitamin E present at about 25 M to about 100 M); a reducing agent (e.g., N-acetylcysteine present at about 0.1 mM to about 5 mM); an agent that prevents calcium entry into cells (e.g., verapamil present at about 2 M to about 25 M); nitroglycerin (e.g., about 0.05 g/L to about 0.2 g/L); an anticoagulant, in one embodiment, present in an amount sufficient to help prevent clotting of residual blood (e.g., heparin or hirudin present at a concentration of about 1000 units/1 to about 100,000 units/1); or an amiloride containing compound (e.g., amiloride, ethyl isopropyl amiloride, hexamethylene amiloride, dimethyl amiloride or isobutyl amiloride present at about 1.0 M to about 5 M).

5.2.2. Collection and Handling of Placenta

[0182] Generally, a human placenta is recovered shortly after its expulsion after birth. In one embodiment, the placenta is recovered from a patient after informed consent and after a complete medical history of the patient is taken and is associated with the placenta. In one embodiment, the medical history continues after delivery.

[0183] Prior to recovery of perfusate, the umbilical cord blood and placental blood are removed. In certain embodiments, after delivery, the cord blood in the placenta is recovered. The placenta can be subjected to a conventional cord blood recovery process. Typically a needle or cannula is used, with the aid of gravity, to exsanguinate the placenta (see, e.g., Anderson, U.S. Pat. No. 5,372,581; Hessel et al., U.S. Pat. No. 5,415,665). The needle or cannula is usually placed in the umbilical vein and the placenta can be gently massaged to aid in draining cord blood from the placenta. Such cord blood recovery may be performed commercially, e.g., LifeBank Inc., Cedar Knolls, N.J., ViaCord, Cord Blood Registry and CryoCell. In one embodiment, the placenta is gravity drained without further manipulation so as to minimize tissue disruption during cord blood recovery.

[0184] Typically, a placenta is transported from the delivery or birthing room to another location, e.g., a laboratory, for recovery of cord blood and collection of perfusate. The placenta can be transported in a sterile, thermally insulated transport device (maintaining the temperature of the placenta between 20-28 C.), for example, by placing the placenta, with clamped proximal umbilical cord, in a sterile zip-lock plastic bag, which is then placed in an insulated container. In another embodiment, the placenta is transported in a cord blood collection kit substantially as described in U.S. Pat. No. 7,147,626. In one embodiment, the placenta is delivered to the laboratory four to twenty-four hours following delivery. In certain embodiments, the proximal umbilical cord is clamped, for example within 4-5 cm (centimeter) of the insertion into the placental disc prior to cord blood recovery. In other embodiments, the proximal umbilical cord is clamped after cord blood recovery but prior to further processing of the placenta.

[0185] The placenta, prior to collection of the perfusate, can be stored under sterile conditions and at either room temperature or at a temperature of 5 to 25 C. (centigrade). The placenta may be stored for a period of longer than forty eight hours, or for a period of four to twenty-four hours prior to perfusing the placenta to remove any residual cord blood. The placenta can be stored in an anticoagulant solution at a temperature of 5 C. to 25 C. (centigrade). Suitable anticoagulant solutions are well known in the art. For example, a solution of heparin or warfarin sodium can be used. In one embodiment, the anticoagulant solution comprises a solution of heparin (e.g., 1% w/w in 1:1000 solution). In some embodiments, the exsanguinated placenta is stored for no more than 36 hours before placental perfusate is collected.

5.2.3. Placental Perfusion

[0186] Methods of perfusing mammalian placentae and obtaining placental perfusate are disclosed, e.g., in Hariri, U.S. Pat. Nos. 7,045,148 and 7,255,879, and in U.S. Application Publication Nos. 2009/0104164, 2007/0190042 and 20070275362, issued as U.S. Pat. No. 8,057,788, the disclosures of each of which are hereby incorporated by reference herein in their entireties.

[0187] Perfusate can be obtained by passage of perfusion solution, e.g., saline solution, culture medium or cell collection compositions described above, through the placental vasculature. In one embodiment, a mammalian placenta is perfused by passage of perfusion solution through either or both of the umbilical artery and umbilical vein. The flow of perfusion solution through the placenta may be accomplished using, e.g., gravity flow into the placenta. For example, the perfusion solution is forced through the placenta using a pump, e.g., a peristaltic pump. The umbilical vein can be, e.g., cannulated with a cannula, e.g., a TEFLON or plastic cannula, that is connected to a sterile connection apparatus, such as sterile tubing. The sterile connection apparatus is connected to a perfusion manifold.

[0188] In preparation for perfusion, the placenta can be oriented in such a manner that the umbilical artery and umbilical vein are located at the highest point of the placenta. The placenta can be perfused by passage of a perfusion solution through the placental vasculature, or through the placental vasculature and surrounding tissue. In one embodiment, the umbilical artery and the umbilical vein are connected simultaneously to a pipette that is connected via a flexible connector to a reservoir of the perfusion solution. The perfusion solution is passed into the umbilical vein and artery. The perfusion solution exudes from and/or passes through the walls of the blood vessels into the surrounding tissues of the placenta, and is collected in a suitable open vessel from the surface of the placenta that was attached to the uterus of the mother during gestation. The perfusion solution may also be introduced through the umbilical cord opening and allowed to flow or percolate out of openings in the wall of the placenta which interfaced with the maternal uterine wall. In another embodiment, the perfusion solution is passed through the umbilical veins and collected from the umbilical artery, or is passed through the umbilical artery and collected from the umbilical veins, that is, is passed through only the placental vasculature (fetal tissue).

[0189] In one embodiment, for example, the umbilical artery and the umbilical vein are connected simultaneously, e.g., to a pipette that is connected via a flexible connector to a reservoir of the perfusion solution. The perfusion solution is passed into the umbilical vein and artery. The perfusion solution exudes from and/or passes through the walls of the blood vessels into the surrounding tissues of the placenta, and is collected in a suitable open vessel from the surface of the placenta that was attached to the uterus of the mother during gestation. The perfusion solution may also be introduced through the umbilical cord opening and allowed to flow or percolate out of openings in the wall of the placenta which interfaced with the maternal uterine wall. Placental cells that are collected by this method, which can be referred to as a pan method, are typically a mixture of fetal and maternal cells.

[0190] In another embodiment, the perfusion solution is passed through the umbilical veins and collected from the umbilical artery, or is passed through the umbilical artery and collected from the umbilical veins. Placental cells collected by this method, which can be referred to as a closed circuit method, are typically almost exclusively fetal.

[0191] The closed circuit perfusion method can, in one embodiment, be performed as follows. A post-partum placenta is obtained within about 48 hours after birth. The umbilical cord is clamped and cut above the clamp. The umbilical cord can be discarded, or can processed to recover, e.g., umbilical cord stem cells, and/or to process the umbilical cord membrane for the production of a biomaterial. The amniotic membrane can be retained during perfusion, or can be separated from the chorion, e.g., using blunt dissection with the fingers. If the amniotic membrane is separated from the chorion prior to perfusion, it can be, e.g., discarded, or processed, e.g., to obtain stem cells by enzymatic digestion, or to produce, e.g., an amniotic membrane biomaterial, e.g., the biomaterial described in U.S. Application Publication No. 2004/0048796. After cleaning the placenta of all visible blood clots and residual blood, e.g., using sterile gauze, the umbilical cord vessels are exposed, e.g., by partially cutting the umbilical cord membrane to expose a cross-section of the cord. The vessels are identified, and opened, e.g., by advancing a closed alligator clamp through the cut end of each vessel. The apparatus, e.g., plastic tubing connected to a perfusion device or peristaltic pump, is then inserted into each of the placental arteries. The pump can be any pump suitable for the purpose, e.g., a peristaltic pump. Plastic tubing, connected to a sterile collection reservoir, e.g., a blood bag such as a 250 mL collection bag, is then inserted into the placental vein. Alternatively, the tubing connected to the pump is inserted into the placental vein, and tubes to a collection reservoir(s) are inserted into one or both of the placental arteries. The placenta is then perfused with a volume of perfusion solution, e.g., about 750 ml of perfusion solution. Cells in the perfusate are then collected, e.g., by centrifugation.

[0192] In one embodiment, the proximal umbilical cord is clamped during perfusion, and, more specifically, can be clamped within 4-5 cm (centimeter) of the cord's insertion into the placental disc.

[0193] The first collection of perfusion fluid from a mammalian placenta during the exsanguination process is generally colored with residual red blood cells of the cord blood and/or placental blood. The perfusion fluid becomes more colorless as perfusion proceeds and the residual cord blood cells are washed out of the placenta. Generally from 30 to 100 mL of perfusion fluid is adequate to initially flush blood from the placenta, but more or less perfusion fluid may be used depending on the observed results.

[0194] In certain embodiments, cord blood is removed from the placenta prior to perfusion (e.g., by gravity drainage), but the placenta is not flushed (e.g., perfused) with solution to remove residual blood. In certain embodiments, cord blood is removed from the placenta prior to perfusion (e.g., by gravity drainage), and the placenta is flushed (e.g., perfused) with solution to remove residual blood.

[0195] The volume of perfusion liquid used to perfuse the placenta may vary depending upon the number of placental cells to be collected, the size of the placenta, the number of collections to be made from a single placenta, etc. In various embodiments, the volume of perfusion liquid may be from 50 mL to 5000 mL, 50 mL to 4000 mL, 50 mL to 3000 mL, 100 mL to 2000 mL, 250 mL to 2000 mL, 500 mL to 2000 mL, or 750 mL to 2000 mL. Typically, the placenta is perfused with 700-800 mL of perfusion liquid following exsanguination.

[0196] The placenta can be perfused a plurality of times over the course of several hours or several days. Where the placenta is to be perfused a plurality of times, it may be maintained or cultured under aseptic conditions in a container or other suitable vessel, and perfused with a cell collection composition, or a standard perfusion solution (e.g., a normal saline solution such as phosphate buffered saline (PBS) with or without an anticoagulant (e.g., heparin, warfarin sodium, coumarin, bishydroxycoumarin), and/or with or without an antimicrobial agent (e.g., -mercaptoethanol (0.1 mM); antibiotics such as streptomycin (e.g., at 40-100 g/ml), penicillin (e.g., at 40 U/ml), amphotericin B (e.g., at 0.5 g/ml). In one embodiment, an isolated placenta is maintained or cultured for a period of time without collecting the perfusate, such that the placenta is maintained or cultured for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, or 24 hours, or 2 or 3 or more days before perfusion and collection of perfusate. The perfused placenta can be maintained for one or more additional time(s), e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 or more hours, and perfused a second time with, e.g., 700-800 mL perfusion fluid. The placenta can be perfused 1, 2, 3, 4, 5 or more times, for example, once every 1, 2, 3, 4, 5 or 6 hours. In one embodiment, perfusion of the placenta and collection of perfusion solution, e.g., placental cell collection composition, is repeated until the number of recovered nucleated cells falls below 100 cells/ml. The perfusates at different time points can be further processed individually to recover time-dependent populations of cells, e.g., total nucleated cells. Perfusates from different time points can also be pooled.

5.2.4. Placental Perfusate and Placental Perfusate Cells

[0197] Typically, placental perfusate from a single placental perfusion comprises about 100 million to about 500 million nucleated cells, including hematopoietic cells from which NK cells, e.g., NK cells produced according to the three-stage method described herein, may be produced by the method disclosed herein. In certain embodiments, the placental perfusate or perfusate cells comprise CD34.sup.+ cells, e.g., hematopoietic stem or progenitor cells. Such cells can, in a more specific embodiment, comprise CD34.sup.+CD45.sup. stem or progenitor cells, CD34.sup.+CD45.sup.+ stem or progenitor cells, or the like. In certain embodiments, the perfusate or perfusate cells are cryopreserved prior to isolation of hematopoietic cells therefrom. In certain other embodiments, the placental perfusate comprises, or the perfusate cells comprise, only fetal cells, or a combination of fetal cells and maternal cells.

In specific embodiments, the placental cells are obtained from placental tissue that has been mechanically and/or enzymatically disrupted.

5.2.6.1. Obtaining PiNK Cells from Placental Perfusate

[0215] In one embodiment, PiNK cells are collected by obtaining placental perfusate, then contacting the placental perfusate with a composition that specifically binds to CD56.sup.+ cells, e.g., an antibody against CD56, followed by isolating of CD56.sup.+ cells on the basis of said binding to form a population of CD56.sup.+ cells. The population of CD56.sup.+ cells comprises an isolated population of natural killer cells. In a specific embodiment, CD56.sup.+ cells are contacted with a composition that specifically binds to CD16.sup.+ cells, e.g., an antibody against CD16, and the CD16.sup.+ cells are excluded from the population of CD56.sup.+ cells. In another specific embodiment, CD3.sup.+ cells are also excluded from the population of CD56.sup.+ cells.

[0216] In one embodiment, PiNK cells are obtained from placental perfusate as follows. Post-partum human placenta is exsanguinated and perfused, e.g., with about 200-800 mL of perfusion solution, through the placental vasculature only. In a specific embodiment, the placenta is drained of cord blood and flushed, e.g., with perfusion solution, through the placental vasculature to remove residual blood prior to said perfusing. The perfusate is collected and processed to remove any residual erythrocytes. Natural killer cells in the total nucleated cells in the perfusate can be isolated on the basis of expression of CD56 and CD16. In certain embodiments, the isolation of PiNK cells comprises isolation using an antibody to CD56, wherein the isolated cells are CD56.sup.+. In another embodiment, the isolation of PiNK cells comprises isolation using an antibody to CD16, wherein the isolated cells are CD16.sup.. In another embodiment, the isolation of PiNK cells comprises isolation using an antibody to CD56, and exclusion of a plurality of non-PiNK cells using an antibody to CD16, wherein the isolated cells comprise CD56.sup.+, CD16.sup. cells.

[0217] Cell separation can be accomplished by any method known in the art, e.g., fluorescence-activated cell sorting (FACS), or, preferably, magnetic cell sorting using microbeads conjugated with specific antibodies. Magnetic cell separation can be performed and automated using, e.g, an AUTOMACS Separator (Miltenyi).

[0218] In another aspect, the process of isolating placental natural killer cells (e.g., PiNK cells) comprises obtaining a plurality of placental cells, and isolating natural killer cells from said plurality of placental cells. In a specific embodiment, the placental cells are, or comprise, placental perfusate cells, e.g., total nucleated cells from placental perfusate. In another specific embodiment, said plurality of placental cells are, or comprise, placental cells obtained by mechanical and/or enzymatic digestion of placental tissue. In another embodiment, said isolating is performed using one or more antibodies. In a more specific embodiment, said one or more antibodies comprises one or more of antibodies to CD3, CD16 or CD56. In a more specific embodiment, said isolating comprises isolating CD56.sup.+ cells from CD56.sup. cells in said plurality of placental cells. In a more specific embodiment, said isolating comprises isolating CD56.sup.+, CD16.sup.placental cells, e.g., placental natural killer cells, e.g., PiNK cells, from placental cells that are CD56.sup. or CD16.sup.+. In a more specific embodiment, said isolating comprises isolating CD56.sup.+, CD16.sup., CD3.sup. placental cells from placental cells that are CD56.sup., CD16.sup.+, or CD3.sup.+. In another embodiment, said process of isolating placental natural killer cells results in a population of placental cells that is at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98% or at least 99% CD56.sup.+, CD16.sup. natural killer cells.

[0219] In certain embodiments, the placental natural killer cells, e.g., PiNK cells, have been expanded in culture. In certain other embodiments, the placental perfusate cells have been expanded in culture. In a specific embodiment, said placental perfusate cells have been expanded in the presence of a feeder layer and/or in the presence of at least one cytokine. In a more specific embodiment, said feeder layer comprises K562 cells or peripheral blood mononuclear cells. In another more specific embodiment, said at least one cytokine is interleukin-2. In specific embodiments, the PiNK cells have been cultured, e.g., expanded in culture, for at least, about, or at most 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 or 28 days. In a specific embodiment, the PiNK cells are cultured for about 21 days.

5.2.6.2. Disruption and Digestion of Placental Tissue to Obtain PiNK Cells

[0220] Placental natural killer cells, e.g., PiNK cells, can also be obtained from placental tissue that has been mechanically and/or enzymatically disrupted.

[0221] Placental tissue can be disrupted using one or more tissue-degrading enzymes, e.g., a metalloprotease, a serine protease, a neutral protease, an RNase, or a DNase, or the like. Such enzymes include, but are not limited to, collagenases (e.g., collagenase I, II, III or IV, a collagenase from Clostridium histolyticum, etc.); dispase, thermolysin, elastase, trypsin, LIBERASE, hyaluronidase, and the like. Typically after digestion, the digested tissue is passed through a strainer or filter to remove partially-digested cell clumps, leaving a substantially single-celled suspension.

[0222] After a suspension of placental cells is obtained, natural killer cells can be isolated using, e.g., antibodies to CD3 and CD56. In a specific embodiment, placental natural killer cells are isolated by selecting for cells that are CD56.sup.+ to produce a first cell population; contacting said first cell population with antibodies specific for CD3 and/or CD16; and removing cells from said first cell population that are CD3.sup.+ or CD56.sup.+, thereby producing a second population of cells that is substantially CD56.sup.+ and CD3.sup., CD56.sup.+ and CD16.sup., or CD56.sup.+, CD3.sup. and CD16.sup..

[0223] In one embodiment, magnetic beads are used to isolate placental natural killer cells from a suspension of placental cells. The cells may be isolated, e.g., using a magnetic activated cell sorting (MACS) technique, a method for separating particles based on their ability to bind magnetic beads (e.g., about 0.5-100 m diameter) that comprise one or more specific antibodies, e.g., anti-CD56 antibodies. A variety of useful modifications can be performed on the magnetic microspheres, including covalent addition of antibody that specifically recognizes a particular cell surface molecule or hapten. The beads are then mixed with the cells to allow binding. Cells are then passed through a magnetic field to separate out cells having the specific cell surface marker. In one embodiment, these cells can then isolated and re-mixed with magnetic beads coupled to an antibody against additional cell surface markers. The cells are again passed through a magnetic field, isolating cells that bound both the antibodies. Such cells can then be diluted into separate dishes, such as microtiter dishes for clonal isolation.

5.2.7. Methods of Producing Activated NK Cells

[0224] Activated NK cells may be produced from hematopoietic cells, which are described above. In certain embodiment, the activated NK cells are produced from expanded hematopoietic cells, e.g., hematopoietic stem cells and/or hematopoietic progenitor cells. In a specific embodiment, the hematopoietic cells are expanded and differentiated, continuously, in a first medium without the use of feeder cells. The cells are then cultured in a second medium in the presence of feeder cells. Such isolation, expansion and differentiation can be performed in a central facility, which provides expanded hematopoietic cells for shipment to decentralized expansion and differentiation at points of use, e.g., hospital, military base, military front line, or the like.

[0225] In some embodiments, production of activated NK cells comprises expanding a population of hematopoietic cells. During cell expansion, a plurality of hematopoietic cells within the hematopoietic cell population differentiate into NK cells.

[0226] In one embodiment, the process of producing a population of activated natural killer (NK) cells comprises: (a) seeding a population of hematopoietic stem or progenitor cells in a first medium comprising interleukin-15 (IL-15) and, optionally, one or more of stem cell factor (SCF) and interleukin-7 (IL-7), wherein said IL-15 and optional SCF and IL-7 are not comprised within an undefined component of said medium, such that the population expands, and a plurality of hematopoietic stem or progenitor cells within said population of hematopoietic stem or progenitor cells differentiate into NK cells during said expanding; and (b) expanding the cells from step (a) in a second medium comprising interleukin-2 (IL-2), to produce a population of activated NK cells.

[0227] In another embodiment, activated NK cells as described herein are produced by a two-step process of expansion/differentiation and maturation of NK cells. The first and second steps comprise culturing the cells in media with a unique combination of cellular factors. In certain embodiments, the process involves (a) culturing and expanding a population of hematopoietic cells in a first medium, wherein a plurality of hematopoietic stem or progenitor cells within the hematopoietic cell population differentiate into NK cells; and (b) expanding the NK cells from step (a) in a second medium, wherein the NK cells are further expanded and differentiated, and wherein the NK cells are maturated (e.g., activated or otherwise possessing cytotoxic activity). In certain embodiments, the process includes no intermediary steps between step (a) and (b), no additional culturing steps prior to step (a), and/or no additional steps (e.g., maturation step) after step (b).

[0229] Without wishing to be bound by any parameter, mechanism or theory, culture of the hematopoietic cells as described herein results in continuous expansion of the hematopoietic cells and differentiation of NK cells from said cells. In certain embodiments, hematopoietic cells, e.g., stem cells or progenitor cells, used in the processes described herein are expanded and differentiated in the first step using a feeder layer. In other embodiments, hematopoietic cells, e.g., stem cells or progenitor cells, are expanded and differentiated in the first step without the use of a feeder layer.

[0230] Feeder cell-independent expansion and differentiation of hematopoietic cells can take place in any container compatible with cell culture and expansion, e.g., flask, tube, beaker, dish, multiwell plate, bag or the like. In a specific embodiment, feeder cell-independent expansion of hematopoietic cells takes place in a bag, e.g., a flexible, gas-permeable fluorocarbon culture bag (for example, from American Fluoroseal). In a specific embodiment, the container in which the hematopoietic cells are expanded is suitable for shipping, e.g., to a site such as a hospital or military zone wherein the expanded NK cells are further expanded and differentiated.

[0286] In a specific embodiment, expansion of the hematopoietic cells is performed in IMDM supplemented with 20% BITS (bovine serum albumin, recombinant human insulin and transferrin), SCF, Flt-3 ligand, IL-3, and 4-(Amino)-2-(2,6-dioxo(3-piperidyl))-isoindoline-1,3-dione (10 M in 0.05% DMSO). In a more specific embodiment, about 510.sup.7 hematopoietic cells, e.g., CD34.sup.+ cells, are expanded in the medium to from about 510.sup.10 cells to about 510.sup.12 cells, which are resuspended in 100 mL of IMDM to produce a population of expanded hematopoietic cells. The population of expanded hematopoietic cells is preferably cryopreserved to facilitate shipping.

[0287] In various specific embodiments, at least 50%, 55%, 60%, 65%, 70%. 75%, 80%, 85%, 90%, 95%, 97%, 98%, or 99% of the hematopoietic cells are differentiated to NK cells.

[0288] In certain embodiments, the process of expansion and differentiation of the hematopoietic cells, as described herein, comprises maintaining the cell population comprising said hematopoietic cells at between about 210.sup.4 and about 210.sup.5 cells per milliliter during expansion and differentiation. In certain other embodiments, the process of expansion and differentiation of the hematopoietic cells, as described herein, comprises maintaining the cell population comprising said hematopoietic cells at no more than about 110.sup.5 cells per milliliter.

[0289] The time for expansion and differentiation of hematopoietic cells into NK cells can be, for example, from about 3 days to about 120 days. In one embodiment, the differentiation time is about 7 days to about 75 days. In another embodiment, the differentiation time is about 14 days to about 50 days. In a specific embodiment, the differentiation time is about 21 days to about 28 days.

5.2.7.2. Second Step

[0290] The hematopoietic cells, e.g., stem cells or progenitor cells, and natural killer cells, resulting from the first step, are further expanded and differentiated in a second step, e.g., without the use of feeder layer or in the presence of feeder cells. Culture of the cells as described herein results in continuous expansion, differentiation as well as maturation of the NK cells from the first step. In the second step, the NK cells are expanded, differentiated and maturated, in a continuous fashion, in a second culture medium, e.g., comprising different cytokines and/or bioactive molecules than said first medium. In certain embodiments, the second culture medium is an animal component-free medium. Exemplary animal component-free cell culture media are described in the disclosure.

[0291] Thus, in one aspect, described herein is a process of producing activated NK cells, comprising expanding the NK cells from the first step, described above, in a second medium in the presence of feeder cells and in contact with interleukin-2 (IL-2). In specific embodiments, said second medium comprises cell growth medium comprising IL-2, e.g., 10 IU/mL to 1000 IU/mL, and one or more of: human serum (e.g., human serum AB), fetal bovine serum (FBS) or fetal calf serum (FCS), e.g., 5%-15% FCS v/v; transferrin, e.g., 10 g/mL to 50 g/mL; insulin, e.g., 5 g/mL to 20 g/mL; ethanolamine, e.g., 510.sup.4 to 510.sup.5M; oleic acid, e.g., 0.1 g/mL to 5 g/mL; linoleic acid, e.g., 0.1 g/mL to 5 g/mL; palmitic acid, e.g., 0.05 g/mL to 2 g/mL; bovine serum albumin (BSA), e.g., 1 g/mL to 5 g/mL; and/or phytohemagglutinin, e.g., 0.01 g/mL to 1 g/mL. In a more specific embodiment, said second medium comprises cell growth medium comprising FBS or FCS, e.g., 10% FCS v/v, IL-2, transferrin, insulin, ethanolamine, oleic acid, linoleic acid, palmitic acid, bovine serum albumin (BSA) and phytohemagglutinin. In a more specific embodiment, said second medium comprises Iscove's Modified Dulbecco's Medium (IMDM), 10% FBS or FCS, 400 IU IL-2, 35 g/mL transferrin, 5 g/mL insulin, 210.sup.5M ethanolamine, 1 g/mL oleic acid, 1 g/mL linoleic acid (Sigma-Aldrich), 0.2 g/mL palmitic acid (Sigma-Aldrich), 2.5 g/mL BSA (Sigma-Aldrich) and 0.1 g/mL phytohemagglutinin.

[0292] In certain embodiments, the second medium does not comprise one or more of, granulocyte colony-stimulating factor (G-CSF), granulocyte/macrophage colony stimulating factor (GM-CSF), interleukin-6 (IL-6), macrophage inflammatory Protein 1 a (MIP1a), or leukemia inhibitory factor (LIF).

[0293] Feeder cells, when used, can be established from various cell types. Examples of these cell types include, without limitation, fibroblasts, stem cells (e.g., tissue culture-adherent placental stem cells), blood cells (e.g., peripheral blood mononuclear cells (PBMC)), and cancerous cells (e.g., chronic myelogenous leukemia (CIVIL) cells such as K562). In a specific embodiment, said culturing in said second medium comprises culturing using feeder cells, e.g., K562 cells and/or peripheral blood mononuclear cells (PBMCs), e.g., at the time the cells are started in said second medium, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 days thereafter. In certain embodiments, feeder cells are optionally from a different species as the cells they are supporting. For example, human NK cells can be supported by mouse embryonic fibroblasts (from primary culture or a telomerized line).

[0294] In certain embodiments, feeder cells are optionally inactivated by irradiation (e.g., -irradiation) or treatment with an anti-mitotic agent such as mitomycin C, to prevent them from outgrowing the cells they are supporting, but permit synthesis of important factors that support the NK cells. For example, cells can be irradiated at a dose to inhibit proliferation but permit synthesis of important factors that support human embryonic stem (hES) cells (about 4000 rads gamma irradiation).

[0295] Culture of NK cells for the second step can take place in any container compatible with cell culture and expansion, e.g., flask, tube, beaker, dish, multiwell plate, bag or the like. In a specific embodiment, feeder cell-dependent culture of NK cells takes place in a bag, e.g., a flexible, gas-permeable fluorocarbon culture bag (for example, from American Fluoroseal). In a specific embodiment, the container in which the NK cells are cultured is suitable for shipping, e.g., to a site such as a hospital or military zone wherein the expanded NK cells are further expanded, differentiated and maturated.

[0296] Differentiation of the cells from step 1 into activated NK cells can be assessed by detecting NK cell-specific markers, e.g., by flow cytometry. NK cell-specific markers include, but are not limited to, CD56, CD94, CD117 and NKp46. Differentiation can also be assessed by the morphological characteristics of NK cells, e.g., large size, high protein synthesis activity in the abundant endoplasmic reticulum (ER), and/or preformed granules.

[0297] The time for expansion and differentiation of cells from step 1 into activated NK cells can be, for example, from about 3 days to about 120 days. In one embodiment, the differentiation time is about 7 days to about 75 days. In another embodiment, the differentiation time is about 14 days to about 50 days. In a specific embodiment, the differentiation time is about 10 days to about 21 days.

[0298] Differentiation of hematopoietic cells into NK cells can be assessed by detecting markers, e.g., CD56, CD94, CD117, NKG2D, DNAM-1 and NKp46, by, for example, flow cytometry. Differentiation can also be assessed by the morphological characteristics of NK cells, e.g., large size, high protein synthesis activity in the abundant endoplasmic reticulum (ER), and/or preformed granules. Maturation of NK cells (e.g., activated NK cells) can be assessed by detecting one or more functionally relevant makers, for example, CD94, CD161, NKp44, DNAM-1, 2B4, NKp46, CD94, KIR, and the NKG2 family of activating receptors (e.g., NKG2D). Maturation of NK cells (e.g., activated NK cells) can also be assessed by detecting specific markers during different developmental stages. For example, in one embodiment, pro-NK cells are CD34.sup.+, CD45RA.sup.+, CD10.sup.+, CD117.sup. and/or CD161.sup.. In another embodiment, pre-NK cells are CD34.sup.+, CD45RA.sup.+, CD10.sup., CD117.sup.+, and/or CD161.sup.. In another embodiment, immature NK cells are CD34.sup., CD117.sup.+, CD161.sup.+, NKp46.sup. and/or CD94/NKG2A.sup.. In another embodiment, CD56.sup.bright NK cells are CD117.sup.+, NKp46.sup.+, CD94/NKG2A.sup.+, CD16.sup., and/or KIR.sup.+/. In another embodiment, CD56.sup.dim NK cells are CD117.sup., NKp46.sup.+, CD94/NKG2A.sup.+/, CD16+, and/or KIR.sup.+. In a specific embodiment, maturation of NK cells (e.g., activated NK cells) is determined by the percentage of NK cells (e.g., activated NK cells) that are CD161.sup., CD94.sup.+ and/or NKp46.sup.+. In a more specific embodiment, at least 10%, 20%, 25%, 30%, 35%, 40%, 50%, 55%, 60%, 65% or 70% of mature NK cells (e.g., activated NK cells) are NKp46.sup.+. In another more specific embodiment, at least 10%, 20%, 25%, 30%, 35%, 40%, 45% or 50% of mature NK cells (e.g., activated NK cells) are CD94.sup.+. In another more specific embodiment, at least 10%, 20%, 25%, 30%, 35%, 40%, 45% or 50% of mature NK cells (e.g., activated NK cells) are CD161.sup..

[0299] In certain embodiments, the differentiation of hematopoietic cells into NK cells are assessed by detecting the expression level of, e.g., CD3, CD7 or CD127, CD10, CD14, CD15, CD16, CD33, CD34, CD56, CD94, CD117, CD161, NKp44, NKp46, NKG2D, DNAM-1, 2B4 or TO-PRO-3, using, e.g., antibodies to one or more of these cell markers. Such antibodies can be conjugated to a detectable label, for example, as fluorescent label, e.g., FITC, R-PE, PerCP, PerCP-Cy5.5, APC, APC-Cy7 or APC-H7.

5.2.10. Isolation of Cells

[0337] Methods of isolating natural killer cells are known in the art and can be used to isolate the natural killer cells, e.g., activated NK cells or TSPNK cells (e.g., NK progenitor cells) produced using the three-step process, described herein. NK cells can be isolated or enriched by staining cells from a tissue source, e.g., peripheral blood, with antibodies to CD56 and CD3, and selecting for CD56.sup.+CD3.sup. cells. NK cells, e.g., activated NK cells or TSPNK cells, can be isolated using a commercially available kit, for example, the NK Cell Isolation Kit (Miltenyi Biotec). NK cells, e.g., activated NK cells or TSPNK cells, can also be isolated or enriched by removal of cells other than NK cells in a population of cells that comprise the NK cells, e.g., activated NK cells or TSPNK cells. For example, NK cells, e.g., activated NK cells or TSPNK cells, may be isolated or enriched by depletion of cells displaying non-NK cell markers using, e.g., antibodies to one or more of CD3, CD4, CD14, CD19, CD20, CD36, CD66b, CD123, HLA DR and/or CD235a (glycophorin A). Negative isolation can be carried out using a commercially available kit, e.g., the NK Cell Negative Isolation Kit (Dynal Biotech). Cells isolated by these methods may be additionally sorted, e.g., to separate CD16.sup.+ and CD16.sup. cells.

[0338] Cell separation can be accomplished by, e.g., flow cytometry, fluorescence-activated cell sorting (FACS), or, preferably, magnetic cell sorting using microbeads conjugated with specific antibodies. The cells may be isolated, e.g., using a magnetic activated cell sorting (MACS) technique, a method for separating particles based on their ability to bind magnetic beads (e.g., about 0.5-100 m diameter) that comprise one or more specific antibodies, e.g., anti-CD56 antibodies. Magnetic cell separation can be performed and automated using, e.g., an AUTOMACS Separator (Miltenyi). A variety of useful modifications can be performed on the magnetic microspheres, including covalent addition of antibody that specifically recognizes a particular cell surface molecule or hapten. The beads are then mixed with the cells to allow binding. Cells are then passed through a magnetic field to separate out cells having the specific cell surface marker. In one embodiment, these cells can then isolated and re-mixed with magnetic beads coupled to an antibody against additional cell surface markers. The cells are again passed through a magnetic field, isolating cells that bound both the antibodies. Such cells can then be diluted into separate dishes, such as microtiter dishes for clonal isolation.

[0340] Cells, e.g., NK cells produced using the methods described herein, e.g., activated NK cells or TSPNK cells (e.g., NK progenitor cells) produced using the three-step process described herein, or placental perfusate cells comprising hematopoietic stem cells or progenitor cells, or placental perfusate, can be preserved, that is, placed under conditions that allow for long-term storage, or under conditions that inhibit cell death by, e.g., apoptosis or necrosis.

[0341] Placental perfusate can be produced by passage of a cell collection composition through at least a part of the placenta, e.g., through the placental vasculature. The cell collection composition comprises one or more compounds that act to preserve cells contained within the perfusate. Such a placental cell collection composition can comprise an apoptosis inhibitor, necrosis inhibitor and/or an oxygen-carrying perfluorocarbon, as described in related U.S. Application Publication No. 20070190042, the disclosure of which is hereby incorporated by reference in its entirety.

[0342] In one embodiment, perfusate or a population of placental cells are collected from a mammalian, e.g., human, post-partum placenta by bringing the perfusate or population of cells into proximity with a cell collection composition comprising an inhibitor of apoptosis and an oxygen-carrying perfluorocarbon, wherein said inhibitor of apoptosis is present in an amount and for a time sufficient to reduce or prevent apoptosis in the population of placental cells, e.g., adherent placental cells, for example, placental stem cells or placental multipotent cells, as compared to a population of cells not contacted or brought into proximity with the inhibitor of apoptosis. For example, the placenta can be perfused with the cell collection composition, and placental cells, e.g., total nucleated placental cells, are isolated therefrom. In a specific embodiment, the inhibitor of apoptosis is a caspase inhibitor. In another specific embodiment, said inhibitor of apoptosis is a JNK inhibitor. In a more specific embodiment, said JNK inhibitor does not modulate differentiation or proliferation of adherent placental cells, e.g., adherent placental stem cells or adherent placental multipotent cells. In another embodiment, the cell collection composition comprises said inhibitor of apoptosis and said oxygen-carrying perfluorocarbon in separate phases. In another embodiment, the cell collection composition comprises said inhibitor of apoptosis and said oxygen-carrying perfluorocarbon in an emulsion.

In another more specific embodiment, said apoptosis inhibitor and said perfluorocarbon are between about 2 C. and 10 C., or between about 2 C. and about 5 C., at the time of bringing the placental cells into proximity with the cell collection composition. In another more specific embodiment, said bringing into proximity is performed during transport of said population of cells. In another more specific embodiment, said bringing into proximity is performed during freezing and thawing of said population of cells.

[0343] In another embodiment, placental perfusate and/or placental cells can be collected and preserved by bringing the perfusate and/or cells into proximity with an inhibitor of apoptosis and an organ-preserving compound, wherein said inhibitor of apoptosis is present in an amount and for a time sufficient to reduce or prevent apoptosis of the cells, as compared to perfusate or placental cells not contacted or brought into proximity with the inhibitor of apoptosis. In a specific embodiment, the organ-preserving compound is UW solution (described in U.S. Pat. No. 4,798,824; also known as VIASPAN; see also Southard et al., Transplantation 49(2):251-257 (1990) or a solution described in Stern et al., U.S. Pat. No. 5,552,267, the disclosures of which are hereby incorporated by reference in their entireties. In another embodiment, said organ-preserving composition is hydroxyethyl starch, lactobionic acid, raffinose, or a combination thereof.

In another embodiment, placental cells are brought into proximity with said cell collection compound after collection by perfusion.

[0345] Typically, during placental cell collection, enrichment and isolation, it is preferable to minimize or eliminate cell stress due to hypoxia and mechanical stress. In another embodiment of the method, therefore, placental perfusate or a population of placental cells is exposed to a hypoxic condition during collection, enrichment or isolation for less than six hours during said preservation, wherein a hypoxic condition is a concentration of oxygen that is less than normal blood oxygen concentration. In a more specific embodiment, said perfusate or population of placental cells is exposed to said hypoxic condition for less than two hours during said preservation. In another more specific embodiment, said population of placental cells is exposed to said hypoxic condition for less than one hour, or less than thirty minutes, or is not exposed to a hypoxic condition, during collection, enrichment or isolation.

In certain embodiments, the post-thaw cells are re-cryopreserved after being cultured, expanded or differentiated using methods provided herein.

5.3. Genetically Modified NK Cells

[0354] In another aspect, NK cells can be genetically modified to enhance target specificity and/or homing specificity.

[0355] In some embodiments, the genetically modified NK cells are NK cells that comprise a chimeric antigen receptor (CAR). CAR is an artificial membrane-bound protein that directs an immune cell (e.g., a T lymphocyte) to an antigen, and stimulates the immune cell to kill a cell displaying the antigen. See, e.g., Eshhar, U.S. Pat. No. 7,741,465; U.S. Patent Application Publication No. 2012/0093842; International Application Publication No. WO 2014/100385; and International Application Publication No. WO 2014/124143. At a minimum, the CAR comprises an extracellular domain that binds to an antigen, e.g., an antigen on a cell, a transmembrane domain, and an intracellular (cytoplasmic) signaling domain (i.e., intracellular stimulatory domain) that transmits a primary activation signal to an immune cell. All other conditions being satisfied, when the CAR is expressed on the surface of, e.g., a T lymphocyte, for example, a primary T lymphocyte, and the extracellular domain of the CAR binds to an antigen, the intracellular signaling domain transmits a signal to the T lymphocyte to activate and/or proliferate, and, if the antigen is present on a cell surface, to kill the cell expressing the antigen. Because some immune cells, e.g., T lymphocytes and NK cells, require two signals, a primary activation signal and a costimulatory signal, in order to maximally activate, CARs can also optionally comprise a costimulatory domain such that binding of the antigen to the extracellular domain results in transmission of both a primary activation signal and a costimulatory signal.

[0356] Adaptive immune responses are initiated in secondary lymphoid organs, including the lymph nodes. B cells and T cells are sequestered in distinct regions of the lymph nodes, termed the B cell zone, located in the outer cortex of the lymph node, or follicles, and the T cell zone, which is more diffusely distributed in the area surrounding the follicles (also known as the paracortex) respectively. B cells and T cells express receptors that allow them to home to these respective zones so that they can be exposed to antigen. Intact antigens are present in the B cell zone, whereas in the T cell zone, antigens are presented by antigen-presenting cells, such as dendritic cells. Intact antigens, such as tumor antigens, are also present at the site of the tumor.

[0357] In some embodiments, the genetically modified NK cells are NK cells that comprise a homing receptor, which causes a cell comprising said homing receptor to home to a particular anatomical zone, a particular tissue, or a particular type of cell, e.g., B cell zone of the lymph nodes, gastrointestinal tract, or skin.

[0358] In certain embodiments, the genetically modified NK cells are NK cells that comprise both a CAR and a homing receptor as described herein.

[0359] Without wishing to be bound by any particular mechanism or theory, it is thought that when the genetically modified cells herein express homing receptors that cause a cell expressing said homing receptor to home to a particular zone, they are more likely to be exposed to native antigen, where the cells, for example, cells expressing a CAR, are capable of being activated.

[0360] The NK cells that comprise a CAR and/or a homing receptor can be generated by any method known in the art. In some embodiments, the NK cells comprising a CAR and/or a homing receptor are first produced as described in Section 5.2 (e.g., by a two-step process or by a three-step process), and are then engineered to express the CAR and/or the homing receptor by introducing the NK cells to (e.g., by transfection) one or more vectors comprising the nucleic acid sequence(s) encoding the CAR and/or the homing receptor. In some embodiments, the cells (e.g., CD34+ hematopoietic stem cells), from whom NK cells can be produced, are first engineered to express a CAR and/or a homing receptor by introducing to the cells (e.g., by transfection) one or more vectors comprising the nucleic acid sequence(s) encoding the CAR and/or the homing receptor, and are then used to derive NK cells comprising the CAR and/or the homing receptor by any process described in Section 5.2 (e.g., a two-step process or a three-step process).

5.3.1. General CAR Structure and Intracellular Domain

[0361] In certain embodiments, the intracellular domain of the CAR is or comprises an intracellular domain or motif of a protein that is expressed on the surface of immune cells and triggers activation and/or proliferation of said NK cells. Such a domain or motif is able to transmit a primary antigen-binding signal that is necessary for the activation of a NK cell in response to the antigen's binding to the CAR's extracellular portion. Typically, this domain or motif comprises, or is, an ITAM (immunoreceptor tyrosine-based activation motif). ITAM-containing polypeptides suitable for CARs include, for example, the zeta CD3 chain (CD3) or ITAM-containing portions thereof. In a specific embodiment, the intracellular domain is a CD3 intracellular signaling domain. In other specific embodiments, the intracellular domain is from a lymphocyte receptor chain, a TCR/CD3 complex protein, an Fc receptor subunit or an IL-2 receptor subunit.

[0362] In certain embodiments, the CAR additionally comprises one or more co-stimulatory domains or motifs, e.g., as part of the intracellular domain of the polypeptide. The one or more co-stimulatory domains or motifs can be, or comprise, one or more of a co-stimulatory CD27 polypeptide sequence, a co-stimulatory CD28 polypeptide sequence, a co-stimulatory OX40 (CD134) polypeptide sequence, a co-stimulatory 4-1BB (CD137) polypeptide sequence, a co-stimulatory inducible T-cell costimulatory (ICOS) polypeptide sequence, a co-stimulatory PD-1 polypeptide sequence, a co-stimulatory CTLA-4 polypeptide sequence, a co-stimulatory NKp46 polypeptide sequence, a co-stimulatory NKp44 polypeptide sequence, a co-stimulatory NKp30 polypeptide sequence, a co-stimulatory NKG2D polypeptide sequence, a co-stimulatory DAP10 polypeptide sequence, a co-stimulatory DAP12 polypeptide sequence, or other costimulatory domain or motif.

[0363] The transmembrane region can be any transmembrane region that can be incorporated into a functional CAR, typically a transmembrane region from a CD4 or a CD8 molecule.

5.3.2. CAR Extracellular Domain

[0364] The extracellular domain of the polypeptide binds to an antigen of interest. In certain embodiments, the extracellular domain comprises a receptor, or a portion of a receptor, that binds to said antigen. The extracellular domain may be, e.g., a receptor, or a portion of a receptor, that binds to said antigen. In certain embodiments, the extracellular domain comprises, or is, an antibody or an antigen-binding portion thereof. In specific embodiments, the extracellular domain comprises, or is, a single-chain Fv domain. The single-chain Fv domain can comprise, for example, a V.sub.L linked to V.sub.H by a flexible linker, wherein said V.sub.L and V.sub.H are from an antibody that binds said antigen.

[0365] The antigen to which the extracellular domain of the polypeptide binds can be any antigen of interest, e.g., can be an antigen on a tumor cell or an antigen on an infected cell. The tumor cell may be, e.g., a cell in a solid tumor, or a cell of a blood cancer. The antigen can be any antigen that is expressed on a cell of any tumor or cancer type, e.g., cells of a lymphoma, a lung cancer, a breast cancer, a prostate cancer, an adrenocortical carcinoma, a thyroid carcinoma, a nasopharyngeal carcinoma, a melanoma, e.g., a malignant melanoma, a skin carcinoma, a colorectal carcinoma, a desmoid tumor, a desmoplastic small round cell tumor, an endocrine tumor, an Ewing sarcoma, a peripheral primitive neuroectodermal tumor, a solid germ cell tumor, a hepatoblastoma, a neuroblastoma, a non-rhabdomyosarcoma soft tissue sarcoma, an osteosarcoma, a retinoblastoma, a rhabdomyosarcoma, a Wilms tumor, a glioblastoma, a myxoma, a fibroma, a lipoma, or the like.

5.3.6. Polynucleotide for Generating CAR and/or Homing Receptor

[0394] Described herein are polynucleotide sequences (i.e., nucleic acid sequences) that encode the chimeric receptors and homing receptors. The polynucleotides may be contained within any polynucleotide vector suitable for the transformation of immune cells, e.g., NK cells. For example, NK cells may be transformed using synthetic vectors, lentiviral or retroviral vectors, autonomously replicating plasmids, a virus (e.g., a retrovirus, lentivirus, adenovirus, or herpes virus), or the like, containing polynucleotides encoding the first and second polypeptides (e.g., chimeric receptors). Lentiviral vectors suitable for transformation of NK cells include, but are not limited to, e.g., the lentiviral vectors described in U.S. Pat. Nos. 5,994,136; 6,165,782; 6,428,953; 7,083,981; and 7,250,299, the disclosures of which are hereby incorporated by reference in their entireties. HIV vectors suitable for transformation of NK cells include, but are not limited to, e.g., the vectors described in U.S. Pat. No. 5,665,577, the disclosure of which is hereby incorporated by reference in its entirety.

[0395] Nucleic acids useful in the production of the polypeptides described herein, e.g., within a NK cell, include DNA, RNA, or nucleic acid analogs. Nucleic acid analogs can be modified at the base moiety, sugar moiety, or phosphate backbone, and can include deoxyuridine substitution for deoxythymidine, 5-methyl-2-deoxycytidine or 5-bromo-2-deoxycytidine substitution for deoxycytidine. Modifications of the sugar moiety can include modification of the 2 hydroxyl of the ribose sugar to form 2-O-methyl or 2-O-allyl sugars. The deoxyribose phosphate backbone can be modified to produce morpholino nucleic acids, in which each base moiety is linked to a six membered, morpholino ring, or peptide nucleic acids, in which the deoxyphosphate backbone is replaced by a pseudopeptide backbone and the four bases are retained. See, for example, Summerton and Weller (1997) Antisense Nucleic Acid Drug Dev. 7:187-195; and Hyrup et al. (1996) Bioorgan. Med. Chain. 4:5-23. In addition, the deoxyphosphate backbone can be replaced with, for example, a phosphorothioate or phosphorodithioate backbone, a phosphoroamidite, or an alkyl phosphotriester backbone.

[0396] A nucleic acid encoding a polypeptide described herein may be introduced into host cells as part of a vector, such as, e.g., an expression vector. In addition, a polypeptide described herein may be produced by transfecting a host cell with a nucleic acid encoding such a polypeptide, and such nucleic acid may be part of a vector. In a specific embodiment, the vector is an expression vector that is capable of directing the expression of a nucleic acid encoding a polypeptide described herein. Non-limiting examples of expression vectors include, but are not limited to, plasmids and viral vectors, such as replication defective retroviruses, adenoviruses, adeno-associated viruses, Newcastle disease virus, vaccinia virus and baculoviruses. Standard molecular biology techniques may be used to introduce a nucleic acid encoding a polypeptide described herein into an expression vector.

[0397] An expression vector comprises a nucleic acid encoding a polypeptide described herein in a form suitable for expression of the nucleic acid in a host cell or non-human subject. In a specific embodiment, an expression vector includes one or more regulatory sequences, selected on the basis of the host cells to be used for expression, which is operably linked to the nucleic acid to be expressed. Within an expression vector, operably linked is intended to mean that a nucleic acid of interest is linked to the regulatory sequence(s) in a manner which allows for expression of the nucleic acid (e.g., in an in vitro transcription/translation system or in a host cell when the vector is introduced into the host cell). Regulatory sequences include promoters, enhancers and other expression control elements (e.g., polyadenylation signals). Regulatory sequences include those which direct constitutive expression of a nucleic acid in many types of host cells, those which direct expression of the nucleic acid only in certain host cells (e.g., tissue-specific regulatory sequences), and those which direct the expression of the nucleic acid upon stimulation with a particular agent (e.g., inducible regulatory sequences). It will be appreciated by those skilled in the art that the design of the expression vector can depend on such factors as, e.g., the choice of the host cell to be transformed, the level of expression of protein desired, etc.

[0398] An expression vector can be introduced into host cells via conventional transformation or transfection techniques. Such techniques include, but are not limited to, calcium phosphate or calcium chloride co-precipitation, DEAE-dextran-mediated transfection, lipofection, and electroporation. Suitable methods for transforming or transfecting host cells can be found in Sambrook et al., 1989, Molecular CloningA Laboratory Manual, 2nd Edition, Cold Spring Harbor Press, New York, and other laboratory manuals. In certain embodiments, a host cell is transiently transfected with an expression vector containing a nucleic acid encoding a polypeptide described herein. In other embodiments, a host cell is stably transfected with an expression vector containing a nucleic acid encoding a polypeptide described herein.

[0399] Cells containing any of the polynucleotide may be selected using one or more selectable markers.

In certain embodiments, antibodies described herein are IgG antibodies, or a class (e.g., human IgG.sub.1, IgG.sub.2, or IgG.sub.4) or subclass thereof. In certain embodiments, antibodies described herein are IgG.sub.2 antibodies (e.g., human IgG.sub.2) or a subclass thereof (e.g., human IgG.sub.2a or human IgG.sub.2b, or a mixture thereof). In certain embodiments, antibodies described herein are IgG.sub.1 antibodies (e.g., human IgG.sub.1) or a subclass thereof. In certain embodiments, IgG.sub.1 antibodies described herein comprise one or more amino acid substitutions and/or deletions in the constant region.

[0406] As used herein, the term monoclonal antibody is a well known term of art that refers to an antibody obtained from a population of homogenous or substantially homogeneous antibodies. The term monoclonal is not limited to any particular method for making the antibody. Generally, a population of monoclonal antibodies can be generated by cells, a population of cells, or a cell line. In specific embodiments, a monoclonal antibody, as used herein, is an antibody produced by a single cell or cell line wherein the antibody immunospecifically binds to an epitope as determined, e.g., by ELISA or other antigen-binding or competitive binding assay known in the art. In particular embodiments, a monoclonal antibody can be a chimeric antibody or a humanized antibody. In certain embodiments, a monoclonal antibody is a monovalent antibody or multivalent (e.g., bivalent) antibody.

5.4.1.2. NK Combinations with Bispecific Killer Cell Engagers

[0410] In certain embodiments, the second agent is a bispecific killer cell engager (BiKE).

[0411] BiKEs are reagents that contain two single chain variable fragments (scFvs) and specifically engage both target cells (e.g., tumor cells or infected cells) and NK cells to mediate target cell killing. They are used to colocalize target cells (e.g., tumor cells or infected cells) with NK cells, and thereby triggering NK-cell mediated antibody-dependent cellular cytotoxicity (ADCC). BiKEs can be generated by any method known in the art, for example, as described in Gleanson, M. K., et al., Mol Cancer Ther, 11: 2674-2684 (2012); Vallera, D. A., et al., Cancer Biother Radiopharm, 28: 274-282 (2013); Wiernik, A., et al., Clin Cancer Res, 19: 3844-3855 (2013); Reiners, K. S., et al., Mol Ther, 21: 895-903 (2013); Singer, H., et al., J Immunother, 33: 599-608 (2010); or Gleason, M. K., et al., Blood, 123: 3016-3026 (2014). One scFv of BiKE specifically binds to an antigen on the surface of target cells (e.g., tumor cells or infected cells), and the other scFv specifically binds to a receptor (e.g., an Fc receptor, such as CD16) on NK cells.

[0412] In specific embodiments, the BiKE comprises a first scFv that specifically binds to a TAA, which is described in Section 5.3.2. In further specific embodiments, the BiKE comprises a second scFv that specifically binds to CD16.

In certain specific embodiments, the cells or the second agent are delivered via intracranial or intravertebral needles and/or catheters with or without pump devices.

[0442] In specific embodiments, the step of administering to said subject an isolated population of NK cells or a pharmaceutical composition thereof is by injection. In specific embodiments, the injection of NK cells is local injection. In more specific embodiments, the local injection is directly into a solid tumor (e.g., a sarcoma). In specific embodiments, administration of NK cells is by injection by syringe. In specific embodiments, administration of NK cells by injection is aided by laparoscopy, endoscopy, ultrasound, computed tomography, magnetic resonance, or radiology.

[0443] The NK cells, the genetically modified NK cells, or the second agent, can be administered to an individual in a composition, e.g., a matrix, hydrogel, scaffold, or the like.

[0444] In one embodiment, the cells are seeded onto a natural matrix, e.g., a placental biomaterial such as an amniotic membrane material. Such an amniotic membrane material can be, e.g., amniotic membrane dissected directly from a mammalian placenta; fixed or heat-treated amniotic membrane, substantially dry (i.e., <20% H.sub.2O) amniotic membrane, chorionic membrane, substantially dry chorionic membrane, substantially dry amniotic and chorionic membrane, and the like. Preferred placental biomaterials on which placental stem cells can be seeded are described in Hariri, U.S. Application Publication No. 2004/0048796, the disclosure of which is hereby incorporated by reference in its entirety.

[0445] In another embodiment, the cells are suspended in a hydrogel solution suitable for, e.g., injection. Suitable hydrogels for such compositions include self-assembling peptides, such as RAD16. In one embodiment, a hydrogel solution comprising the cells can be allowed to harden, for instance in a mold, to form a matrix having cells dispersed therein for implantation. The cells in such a matrix can also be cultured so that the cells are mitotically expanded prior to implantation. The hydrogel can be, for example, an organic polymer (natural or synthetic) that is cross-linked via covalent, ionic, or hydrogen bonds to create a three-dimensional open-lattice structure that entraps water molecules to form a gel. Hydrogel-forming materials include polysaccharides such as alginate and salts thereof, peptides, polyphosphazines, and polyacrylates, which are crosslinked ionically, or block polymers such as polyethylene oxide-polypropylene glycol block copolymers which are crosslinked by temperature or pH, respectively. In some embodiments, the hydrogel or matrix is biodegradable.

[0446] In some embodiments, the formulation used in the present invention comprises an in situ polymerizable gel (see., e.g., U.S. Patent Application Publication 2002/0022676; Anseth et al., J. Control Release, 78(1-3):199-209 (2002); Wang et al., Biomaterials, 24(22):3969-80 (2003).

[0447] In some embodiments, the polymers are at least partially soluble in aqueous solutions, such as water, buffered salt solutions, or aqueous alcohol solutions, that have charged side groups, or a monovalent ionic salt thereof. Examples of polymers having acidic side groups that can be reacted with cations are poly(phosphazenes), poly(acrylic acids), poly(methacrylic acids), copolymers of acrylic acid and methacrylic acid, poly(vinyl acetate), and sulfonated polymers, such as sulfonated polystyrene. Copolymers having acidic side groups formed by reaction of acrylic or methacrylic acid and vinyl ether monomers or polymers can also be used. Examples of acidic groups are carboxylic acid groups, sulfonic acid groups, halogenated (preferably fluorinated) alcohol groups, phenolic OH groups, and acidic OH groups.

[0448] The cells can be seeded onto a three-dimensional framework or scaffold and implanted in vivo. Such a framework can be implanted in combination with any one or more growth factors, cells, drugs or other components that stimulate tissue formation or otherwise enhance or improve the practice of the methods described herein.

[0449] Examples of scaffolds that can be used in the present invention include nonwoven mats, porous foams, or self assembling peptides. Nonwoven mats can be formed using fibers comprised of a synthetic absorbable copolymer of glycolic and lactic acids (e.g., PGA/PLA) (VICRYL, Ethicon, Inc., Somerville, N.J.). Foams, composed of, e.g., poly(-caprolactone)/poly(glycolic acid) (PCL/PGA) copolymer, formed by processes such as freeze-drying, or lyophilization (see, e.g., U.S. Pat. No. 6,355,699), can also be used as scaffolds.

[0450] The cells can also be seeded onto, or contacted with, a physiologically-acceptable ceramic material including, but not limited to, mono-, di-, tri-, alpha-tri-, beta-tri-, and tetra-calcium phosphate, hydroxyapatite, fluoroapatites, calcium sulfates, calcium fluorides, calcium oxides, calcium carbonates, magnesium calcium phosphates, biologically active glasses such as BIOGLASS, and mixtures thereof. Porous biocompatible ceramic materials currently commercially available include SURGIBONE (CanMedica Corp., Canada), ENDOBON (Merck Biomaterial France, France), CEROS (Mathys, AG, Bettlach, Switzerland), and mineralized collagen bone grafting products such as HEALOS (DePuy, Inc., Raynham, Mass.) and VITOSS, RHAKOSS, and CORTOSS (Orthovita, Malvern, Pa.). The framework can be a mixture, blend or composite of natural and/or synthetic materials.

[0451] In another embodiment, cells can be seeded onto, or contacted with, a felt, which can be, e.g., composed of a multifilament yarn made from a bioabsorbable material such as PGA, PLA, PCL copolymers or blends, or hyaluronic acid.

[0452] The cells can, in another embodiment, be seeded onto foam scaffolds that may be composite structures. Such foam scaffolds can be molded into a useful shape, such as that of a portion of a specific structure in the body to be repaired, replaced or augmented. In some embodiments, the framework is treated, e.g., with 0.1M acetic acid followed by incubation in polylysine, PBS, and/or collagen, prior to inoculation of the cells described herein in order to enhance cell attachment. External surfaces of a matrix may be modified to improve the attachment or growth of cells and differentiation of tissue, such as by plasma-coating the matrix, or addition of one or more proteins (e.g., collagens, elastic fibers, reticular fibers), glycoproteins, glycosaminoglycans (e.g., heparin sulfate, chondroitin-4-sulfate, chondroitin-6-sulfate, dermatan sulfate, keratin sulfate, etc.), a cellular matrix, and/or other materials such as, but not limited to, gelatin, alginates, agar, agarose, and plant gums, and the like.

[0453] In some embodiments, the scaffold comprises, or is treated with, materials that render it non-thrombogenic. These treatments and materials may also promote and sustain endothelial growth, migration, and extracellular matrix deposition. Examples of these materials and treatments include but are not limited to natural materials such as basement membrane proteins such as laminin and Type IV collagen, synthetic materials such as EPTFE, and segmented polyurethaneurea silicones, such as PURSPAN (The Polymer Technology Group, Inc., Berkeley, Calif.). The scaffold can also comprise anti-thrombotic agents such as heparin; the scaffolds can also be treated to alter the surface charge (e.g., coating with plasma) prior to seeding with placental stem cells.

[0454] In specific embodiments, the NK cells, the genetically modified NK cells, or the second agent is administered with a pharmaceutical carrier. The pharmaceutical carrier can be any known in the art. In specific embodiments, the NK cells or the genetically modified NK cells are fucosylated on the cell surface.

[0455] Determination of the number of NK cells or genetically modified NK cells (e.g., NK cells comprising a CAR and/or a homing receptor), or the amount of the second agent can be performed independently. Such determination can be based on the condition of the subject and can be made by the physician.

[0456] In certain embodiments, the NK cells, the genetically modified NK cells, or the second agent, is used, e.g., administered to an individual, in any amount or number that results in a detectable therapeutic benefit to the individual, e.g., an effective amount, wherein the individual has a viral infection, cancer, or tumor cells, for example, an individual having tumor cells, a solid tumor or a blood cancer, e.g., a cancer patient. Cells can be administered to such an individual by absolute numbers of cells, e.g., said individual can be administered at about, at least about, or at most about, 110.sup.5, 510.sup.5, 110.sup.6, 510.sup.6, 110.sup.7, 510.sup.7, 110.sup.8, 510.sup.8, 110.sup.9, 510.sup.9, 110.sup.10, 510.sup.10, or 110.sup.11 cells.

Cells can be administered to such an individual according to an approximate ratio between a number of NK cells or genetically modified NK cells and optionally placental perfusate cells, and a number of tumor/infected cells in said individual (e.g., an estimated number). For example, NK cells or the genetically modified NK cells can be administered to said individual in a ratio of about, at least about or at most about 1:1, 1:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 15:1, 20:1, 25:1, 30:1, 35:1, 40:1, 45:1, 50:1, 55:1, 60:1, 65:1, 70:1, 75:1, 80:1, 85:1, 90:1, 95:1 or 100:1 to the number of tumor/infected cells in the individual. The number of tumor/infected cells in such an individual can be estimated, e.g., by counting the number of tumor/infected cells in a sample of tissue from the individual, e.g., blood sample, biopsy, or the like. In specific embodiments, e.g., for solid tumors, said counting is performed in combination with imaging of the tumor or tumors to obtain an approximate tumor volume.

6. EXAMPLE

6.1. Example 1: Antibody-Dependent Cellular Cytotoxicity (ADCC) Using Rituximab

[0465] The Example presented herein demonstrates that co-administration of NK cells (here, PiNK cells) and an antibody specific for a cell surface antigen (in this case, CD20), e.g., a tumor-associated antigen increases NK antibody-dependent cell-mediated cytotoxicity (ADCC) of the NK cells.

[0466] The experiments presented herein utilize an anti-CD20 antibody, rituximab, and Daudi cells (Cat #: CCL-213, ATCC), which are high expressers of CD20. Daudi cells were harvested and labeled with PKH26 (Cat #: PKH26GL-1KT, Sigma-Aldrich) (Ferlazzo, G., et al., J Immunol, 172: 1455-1462 (2004); Lehmann, D., et al., Stem Cells Dev, 21: 2926-2938 (2012)), whose lipophilic aliphatic residue inserts into cell plasma membrane. The cells were washed and incubated with rituximab (and human IgG as an isotype control) at different concentrations as indicated in FIG. 1 for 1 h at room temperature. After washing three times, 10.sup.4 target cells were placed in 96-well U-bottom tissue culture plates and incubated with cultured NK cells at various effector-target (E:T) ratios (50:1, 20:1, 10:1 and 2.5:1) in 200 l RPMI 1640 supplemented with 10% FBS. The Cultures were incubated for 4 h at 37 C. in 5% CO.sub.2. After incubation, cells were harvested and TO-PRO-3 (Catalog #T3605, Invitrogen), a membrane-impermeable DNA stain, was added to cultures to 0.25 M final concentration followed by FACS analysis using BD FACSCanto II. Cytotoxicity (% cytotoxicity in FIG. 1) is expressed as percentage of dead cells (PKH26.sup.+TO-PRO-3.sup.+) within the total PKH26.sup.+ target tumor cells, subtracted by spontaneous cell death.

[0467] Incubating Daudi cells with rituximab increases the cytotoxicity of (PiNK) cells compared to human IgG controls, thereby indicating enhanced cytolytic activity of PiNK cells when accompanied by co-administration of the anti-CD20 antibody (FIG. 1).

6.2. Example 2: Cytotoxicity of Three-Stage NK Cells Against Multiple Myeloma

[0468] Phenotype Characterization of MM Cell Lines and Primary MM Samples.

[0469] Primary multiple myeloma (MM) cells (Tissue Solution, donor IDs: MM285, MM293) or MM tumor cell lines: RPMI8226 (ATCC, Cat #CCL-155) and OPM2 (DSMZ, Cat #ACC-50) cells (110.sup.6 each) were used for this assay. Cells were stained with anti-PD-L1 APC (Biolegend, Cat #329708), anti-CS1 PE-Cy7 (Biolegend, Cat #331816) and 7-AAD (BD Bioscience, Cat #559925) according to the manufacturer's protocol. Data were acquired on BD LSRFortessa (BD Biosciences) and analyzed using FLOWJO software (Tree Star). Data were expressed as positive cells gated under 7-AAD-single cells. Setting of the % positive gate was done using unstained sample as control.

[0470] Results. The expression of PD-L1 and CS-1 on the MM cells lines is shown in FIG. 2. The left-most peak in the panels of FIG. 2 indicates the control, whereas the right-most peak indicates the sample. The percentage of cells positive for PD-L1 was as follows: 71.6% MM285, 70.7% MM293, 66.2% OPM-2, and 94.4% RPMI8226. The percentage of cells positive for CS-1 was as follows: 31.8% MM285, 58.8% MM293, 93.4% OPM-2, and 29.5% RPMI8226.

[0471] 24-hour Cytotoxicity assay of three-stage NK cells against MM cell lines and primary MM samples. OPM2 cells were labeled with 10 M PKH26 fluorescent dye (Sigma-Aldrich, Cat #PKH26-GL) prior to co-culture with three-stage NK cells from five different donors at an effector to target (E:T) ratio of 3:1 (310.sup.5 and 110.sup.5 three-stage NK and OPM2 cells, respectively) in 1 mL of RPMI1640 supplemented with 10% FBS and antibiotics (Basal medium), or the experimental conditions: IL-15 (5 ng/mL) (Invitrogen, Cat #PHC9153); IL-2 (200 IU/mL) (Invitrogen, Cat #PHC0023); anti-PD-L1 (10 ng/mL) (Affymetrix, Cat #16-5983-82); anti-IgG (long/mL) (Affymetrix, Cat #16-4714-82); REVLIMID (lenalidomide; luM), or DMSO (0.1%) in 48-well plates. Target cells alone were plated as controls. After incubation for 24 hours at 37 C. and 5% CO.sub.2, cells were harvested, followed by staining with 1 M TO-PRO-3 to identify the dead cells. The number of viable target cells (PKH26.sup.+TO-PRO-3.sup.) in each sample was quantified by flow cytometry using counting beads following the protocol provided by the manufacturer (Invitrogen, Cat #C36950). Counting beads were introduced in this assay in order to account for any potential proliferation of tumor cells during the prolonged 24 hour culture.

[0472] Briefly, the number of viable target cells in each sample was calculated as follows: (% PKH26.sup.+TO-PRO-3.sup. live targets)/(% counting beads)(assigned bead count of the counting bead lot). Percent survival (% survival) in samples (target cells with co-cultures of three-stage NK cells) was calculated by dividing the absolute number of viable, PKH26.sup.+, target cells remaining in co-cultures with three-stage NK cells after 24 hours with the absolute number of viable, PKH26.sup.+, target cells remaining in culture of target cells alone. Percent cytotoxicity at 24 hours reported was calculated as: 100-% survival. Results were depicted as meanstandard deviation of the mean.

[0473] Results.

[0474] Three-stage NK cells displayed cytotoxic activity against different MM cell lines. The three-stage NK cells exerted 20-60% specific lysis against four primary MM samples at an E:T ratio of 3:1 (FIG. 3). Varying susceptibility of MM targets from different donors to NK killing was observed. In addition, initial assessment the cytotoxicity of three-stage NK cells against OPM2 indicated an enhancement of cytolytic activity by addition of the cytokines, immunomodulatory compounds, and monoclonal antibodies utilized in these experiments (FIG. 4).
