摘要:
Methods, kits, compositions, and systems are provided for culturing pluripotent stem cells to produce populations of cells comprising beta-like cells (e.g., pancreatic lineage, glucose-responsive, and/or insulin-producing). In particular, culture conditions are provided that result in the generation of beta-like 5 cells from a starting culture of human pluripotent stem cells.
摘要:
The present disclosure relates, in general, to a media, e.g., a serum replacement, media supplement, complete media or cryopreservation media, comprising a base physiological buffer and liposomes comprising cholesterol, phosphatidylcholine and fatty acids. It is contemplated that media provides advantages to improve cell growth in culture compared to cells cultured not using the serum replacement described herein.
摘要:
The present invention provides methods or kits with inflammatory cytokines to pretreat 1-ISCs to augment their immune modulatory effect, in prevention and treatment of various diseases such as multiple sclerosis, arthritis, lupus, sepsis, hepatitis, cirrhosis, Parkinson's disease, chronic infections, and GvHD. The present invention relates to novel methods for enhancing the immunosuppressive or the immune stimulatory activities of mesenchymal stem cells (JvfSCs).

Also provided herein are methods of suppressing tumor cell proliferation, of treating individuals having cancer or a viral infection, comprising administering the NK cells produced by the method to an individual having the cancer or viral infection.
摘要:
The invention relates to a culture medium comprising an inhibitor of the BMP signaling pathway; and an inhibitor of the TGF/activin/nodal signaling pathway and to a method for obtaining a population of neural precursors using said culture medium.
摘要:
A method for producing human dendritic cells for therapeutic purposes which allows culture-deriving dendritic cells using no cytokines, or reduced cytokines. The method involves culturing mononuclear cells from blood or bone marrow in a medium containing at least one agent such as a calcium ionophore, e.g. A23187, theophylline, protaglandin E1, dibutyryl cyclic AMP, Vitamin D3, Vitamin E, retinoic acid, or a fatty acid. The culture is maintained for a sufficient time, typically 4 - 14 days, to produce a culture enriched for dendritic cells, as evidenced by at least about 2.5 % of total cells exhibiting dendritic cell processes, or a dendritic cell antigen such as CD80, CD86, or CD1a. Also provided is a method to produce antigen-specific human T-cells by pulsing the dendritic cells obtained by the method of the invention with an antigen such as a viral, tumor, bacterial, or cell surface antigen, and then co-culturing T-cells with the antigen-pulsed dendritic cells. Useful for treatment of viral or bacterial infections, useful as a cancer vaccine, useful to induce tolerance of allo- or xeno-graft.
