System and method for isolating extracellular vesicles
A system and method of isolating extracellular vesicles. The method includes loading one or more of blood or bone marrow into an input port of a concentration system and centrifuging one or more of the blood or bone marrow to separate one or more of red blood cells, platelet poor plasma, or platelet rich plasma/bone marrow concentrate fractions via a centrifuge device. The method further includes pumping one or more of bone marrow/platelet rich plasma fractions and platelet poor plasma fractions into a receptacle of the concentration system and adding a concentrated aqueous two-phase solution to one or more of the bone marrow concentrate/platelet rich plasma fractions and platelet poor plasma fractions. The method also includes drawing the concentrated aqueous two-phase solution and one or more of the bone marrow concentrate/platelet rich plasma fractions or platelet poor plasma fractions back into the centrifuge device to isolate one or more of extracellular vesicles and platelet rich plasma/bone marrow concentrate fractions.
Device for extracting platelet rich plasma
The present invention relates to a platelet rich plasma (PRP) extracting device and extracting method using the same, and more particularly, to a platelet rich plasma (PRP) extracting device capable of quickly and effectively extracting the highly concentrated PRP from centrifuged blood by a simple manipulation.
MATERIALS AND METHODS FOR PRODUCING BLOOD PRODUCTS
Provided herein are materials and methods for the preparation of blood products. In one aspect, provided herein is a composition including platelets or platelet derivatives and an aqueous medium, wherein the aqueous medium has a protein concentration less than 50% of the protein concentration of donor apheresis plasma.
COMPOSITIONS AND METHODS RELATED TO MEGAKARYOCYTE-DERIVED EXTRACELLULAR VESICLES
Disclosed herein are compositions and methods related to megakaryocyte-derived extracellular vesicles derived from human pluripotent stem cells, where the megakaryocyte-derived extracellular vesicles may be utilized for drug delivery and treating various diseases.
Alginate hydrogel compositions
The present application provides a semi-permeable hydrogel composition comprising an alginate matrix that is covalently crosslinked in its periphery to a multi-armed water soluble polymer, along with related methods and uses thereof.
Method for Determining Prognosis of Cancer
The present invention provides a method for determining the prognosis of cancer in a subject. The method comprises measuring the amount of megakaryocytes in a sample from the subject. Usually, the sample is a blood sample. The method may also comprise measuring the number of circulating tumour cells (CTCs) in the sample, and in some embodiments a comparison of the number of megakaryocytes and CTCs in the sample. The present invention also provides methods of treatment for cancer in a patient for whom a poor prognosis is predicted using a method of prognosis of the invention.
Electrophoresis device
The present invention relates to apparatuses for use in electrophoretic separation of macromolecules and/or cells, and in which circulating buffer streams are not required for the electrophoretic separation of macromolecules and/or cells. In certain embodiments, the electrophoretic apparatus disclosed herein comprise a sample chamber and a harvest chamber separated by a size-exclusion membrane; non-circulating buffer chambers flanking each respective sample chamber and harvest chamber, wherein each buffer chamber is separated from each respective sample chamber and harvest chamber by an ion-permeable membrane (restriction membrane), and wherein the buffer chambers are sealed and contain a buffer solution; and an electrode positioned in each buffer chamber. Also disclosed are related methods of using the electrophoretic apparatus disclosed herein.
CANINE BLOOD PLATELET PREPARATIONS
The present disclosure provides dry and liquid compositions that include canine platelets and/or canine platelet-derived substances in dried form or rehydrated form from a dried form of canine platelets and/or canine platelet-derived substances, as well as processes for preparing such compositions. The disclosure also provides processes for making the compositions and methods of using the compositions for therapeutic, prophylactic, diagnostic, and research purposes, and kits comprising the compositions.
Blood component separation device
A blood component separation device for separating a plurality of blood components from blood sampled from a blood donor, and collecting platelets, includes: an operation unit that calculates a predicted platelet recovery rate from a hematocrit value of the blood and a platelet concentration of the blood, and calculates a recommended processing amount of the blood recommended for collecting a target number of units of platelets on the basis of the calculated predicted platelet recovery rate, wherein the operating unit sets the predicted platelet recovery rate calculated from any the hematocrit value and any the platelet concentration to be smaller by a predetermined value a when the blood donor is female than that when the blood donor is male.
PLATELET RELEASE SYSTEM AND PLATELET RELEASE METHOD
The invention relates to a system for platelet release from a fluid comprising in particular megakaryocytic cells comprising cytoplasmic extensions.
The system allows to reproduce the pipetting process performed manually by means of a pipette, thereby permitting a continuous and automatic release of platelets.
This is performed on a large scale since the geometry of the system according to the invention allows to treat large volumes of fluid with a high flow rate (of the order of a plurality of liters per hour), thereby making it particularly suitable for use on an industrial scale.
The invention also relates to a method for platelet release from a fluid comprising in particular megakaryocytic cells comprising cytoplasmic extensions, said method being implemented by means of the abovementioned system.
