IN-VITRO CULTURE, INDUCTION, ACTIVATION AND CRYOPRESERVATION METHOD AND CELL BANK ESTABLISHMENT FOR IMMUNE CELLS
20230051425 · 2023-02-16 ·

The present invention discloses an in-vitro culture, induction, activation and cryopreservation method and cell bank establishment for immune cells. The method includes the follows: using a dedicated amplification medium of immune cells to perform first-stage amplification culture on mononuclear cells to obtain preliminarily amplified immune cells; using a dedicated induction medium of immune cells to perform second-stage induction and amplification culture on the preliminarily amplified immune cells to obtain induced immune cells; using a dedicated activation medium of immune cells to perform third-stage activation and amplification culture on the induced immune cells to obtain a large number of immune cells with activation functions; using a dedicated cryopreserving fluid of immune cells to cryopreserve the immune cells to obtain cryopreserved immune cells; and performing preservation according to ABO/RH typing and HLA typing; and establishing an information file of immune cells for retrieval to construct an immune cell bank.

COMPOSITION AND USE THEREOF

A composition having cell-derived physiological activity is provided. The composition according to the present invention contains a treated product of megakaryocytes or a culture of the megakaryocytes.

VESICLE AND USE THEREOF

Provided are a vesicle and the use thereof. The vesicle is an induced vesicle, and the sources thereof include stem cells or somatic cells, and the possessed markers include Syntaxin 4. Compared with an exosome in mesenchymal stem cells, the vesicle can specifically express Syntaxin 4 and can be used to distinguish characteristic markers of MSC-derived vesicles and exosomes. The vesicle can play a procoagulant effect in vitro, can improve the bleeding tendency of mice with hemophilia after in vivo injection, and can be used for the treatment of improving the bleeding tendency of hemophilia. In addition, the vesicle can be expelled through the skin and hair.

DIFFERENTIATION METHOD FOR PROCURING LARGE AMOUNT OF CELLS BY CHOPPING 3D ORGANOIDS PREPARED FROM HUMAN PLURIPOTENT STEM CELLS

The present invention relates to a method of patterning and chopping 3D organoids prepared from human pluripotent stem cells, culturing the stem cells or progenitor cells, and inducing the differentiation thereof to obtain a large amount of finally differentiated cells. Compared to cells differentiated by a conventional differentiation method, the cells obtained in a large amount exhibit remarkably superior effects in terms of reproducibility, stability, and functionality, and thus are expected to be very useful for cell therapeutic agents or for the screening of therapeutic drugs.

Method for producing CD4/CD8 double-positive T cells

A method for producing CD4/CD8 double-positive T cells, comprising the steps of: (1) culturing pluripotent stem cells in a medium to induce hematopoietic progenitor cells; and (2) culturing the hematopoietic progenitor cells obtained in the step (1) in a medium containing a p38 inhibitor and/or SDF-1 to induce CD4/CD8 double-positive T cells.

METHOD FOR INDUCING HEPATOCYTE PLASTICITY

The disclosure provides a method for producing hepatocytes or hepatic progenitor cells; a method for suppressing hepatocyte aging using a drug causing histone hyperacetylation; a hepatocyte anti-aging agent; a method for increasing hepatocyte plasticity; and a drug for increasing hepatocyte plasticity.

FIBROCARTILAGE PREPARATION METHOD USING TENSILE STIMULATION

The present invention relates to a fibrocartilage preparation method and fibrocartilage prepared by the method.

COMPOSITIONS AND METHODS FOR GENERATION OF RETINAL GANGLION CELLS FROM INDUCIBLE PLURIPOTENT STEM CELLS FOR THE TREATMENT OF PROGRESSIVE OPTIC NEUROPATHIES, INCLUDING GLAUCOMA

Compositions and methods for inducing pluripotent stem cells into retinal ganglion cells for administration to a subject for treating progressive optic neuropathies, thereby alleviating symptoms of such disorders including glaucoma.

Immunocompatible chorionic membrane products

Provided herein is a placental product comprising an immunocompatible chorionic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.

Media for stem cell proliferation and induction

The present application discloses a cell culture media for growth, maintenance and induction of reversion to a less mature state of a cell comprising a MUC1* activating ligand.
