The disclosure relates methods for increasing the efficiency of cellular reprogramming of somatic cells and improving the maturity of the resulting cells.

Disclosed herein are human hepatocytes for example isolated human hepatic progenitor cells, artificial tissue or organ thereof, and kits or compositions thereof. Also disclosed herein are various methods of using a human hepatocyte disclosed herein.

Chimeric antigen receptors targeted to TAG72 and the use thereof to treat ovarian cancer and other cancers are described

The invention provides improved methods for preparing hematopoietic cells for transplantation and the resulting improved hematopoietic cell compositions. The invention further relates to improved culture media and methods of culturing, processing, modulating, and expanding blood cell products for hematopoietic transplantation.

Methods of inducing a polarization of macrophages. The method includes obtaining a blood fraction, fractionating the blood fraction to produce a blood fraction, and contacting the blood fraction with a source of macrophages. A blood fraction including platelet-poor plasma polarizes the source of macrophages into M1 macrophages. A blood faction including a protein solution polarizes the source of macrophages into M2 macrophages.

The present disclosure generally relates to compositions of NK cells for adoptive transfer. In particular, the disclosure relates to enhancing viability, proliferation and cytotoxicity of feeder-free NK cells following cryopreservation.

Provided herein are methods for producing engineered T cells that express a recombinant receptor, such as for use in cell therapy. In some aspects, the provided methods include one or more steps for incubating the cells under stimulating conditions, introducing a recombinant polypeptide to the cells through transduction or transfection, and/or cultivating the cells under conditions that promote proliferation and/or expansion, in which one or more steps is carried out in the presence of an agent that inhibits mammalian target of rapamycin (mTOR) activity. In some aspects, cultivation is performed in the presence of an agent that inhibits mammalian target of rapamycin (mTOR) activity. In some aspects, the provided methods produce genetically engineered T cells with improved persistence and/or anti-tumor activity in vivo.

In one aspect, engineered hematopoietic stem cells comprising a heterologous expression cassette are provided. In some embodiments, the expression cassette comprises a promoter operably linked to a polynucleotide that encodes a 1α-hydroxylase protein, wherein the 1α-hydroxylase protein is human cytochrome P450 family 27 subfamily B member 1 (CYP27B1).

Provided is a method for producing an economical bovine serum composition containing many factors useful for cell proliferation. The method includes a step of performing an anticoagulation treatment of bovine whole blood with an anticoagulant, a step of obtaining a buffy coat and a fraction with a heavier specific gravity than that of the buffy coat from the anticoagulated whole blood, and a step of promoting and activating an interaction between the obtained leukocytes and platelets at a given temperature for not less than a given time to cause secretion or release of a humoral factor from the leukocytes and/or platelets and performing a recoagulation treatment of blood components including the humoral factor with a re-coagulating agent.

Compositions and methods are provided for generating a clonal population of transfected eukaryotic cells derived from a single cell. The method includes transfecting a population of eukaryotic cells with a multi-cistronic nucleic acid vector followed by non-antibiotic selection and characterization of the selected cells. The multi-cistronic nucleic acid vector encodes a selection element which may be an autocrine protein, miRNA, and/or shRNA.
