摘要:
The present invention relates to a chemically defined medium for eukaryotic cell culture, comprising water, at least one carbon source, one or more vitamins, one or more salts, one or more fatty acids, one or more buffer components, selenium, at least one substance of the group of Functional Inhibitors of Acid Sphingomyelinase (FIASMAs) and at least one polypeptide of the TGF-β superfamily with the ability to inhibit stem cell differentiation, its use in the culture of human pluripotent stem cells, a cell culture system comprising human pluripotent stem cells and the chemically defined medium, as well as a kit for proliferation and/or maintenance of human pluripotent stem cells.
摘要:
The present application provides materials and methods for treating hemoglobinopathies. More specifically, the application provides methods for producing progenitor cells that are genetically modified via genome editing to increase the production of fetal hemoglobin (HbF), as well as modified progenitor cells (including, for example, CD34 + human hematopoietic stem cells) producing increased levels of HbF, and methods of using such cells for treating hemoglobinopathies such as sickle cell anemia and β-thalassemia.
摘要:
The present invention generally relates to methods of preparing leukocytes, particularly T cells, ex vivo for use in immunotherapy, particularly cancer immunotherapy. More specifically, the invention relates to methods for the preparation of leukocytes exhibiting cytotoxic properties for use in adoptive cell transfer. The invention also relates to cells and compositions including them for cancer immunotherapy. The invention also relates to methods of immunotherapy, particularly cancer immunotherapy. The present invention relates to a method for producing a leukocyte that has an enhanced capacity for killing a target cell, the method including contacting the leukocyte with a PTPN2 inhibitor in conditions for enabling the inhibitor to inactivate PTPN2 in the leukocyte, thereby producing a leukocyte that has an enhanced capacity for killing a target cell. Preferably, the leukocyte is contacted with the PTPN2 inhibitor in the absence of a T helper cell.
摘要:
Presented herein is a method for treating a subject afflicted with a tumor comprising administering to the subject a therapeutically effective amount of an agent that inhibits the MSF/Cdc42/NFkB cascade in the subject's tumor-associated fibroblasts.
摘要:
The present disclosure provides compositions and methods for engineering cartilage of clinically-relevant geometry and biomechanical properties. In particular, the present disclosure provides processes involving expansion, redifferentiation and construct formation to provide neocartilage, which resembles native cartilage.
摘要:
Provided is a system and method of maintaining and/or increasing cell viability by downregulating cellular metabolic rate under hypoxic conditions via increasing and/or prolonging the availability of adenosine or derivatives thereof in the cell. Also provided is a system and method of prolonging the survival of implanted cells that are under hypoxic condition until host neovascularization is achieved, via increasing and/or prolonging the availability of adenosine or derivatives there in the cells. Also provided is a system and method of maintaining and/or increasing cell viability by downregulating cellular metabolic rate under hypoxic conditions via applying at least one purine metabolism enzyme inhibitor to the cell.
摘要:
This invention relates to novel a-galactosidases for the enzymatic removal of the immunodominant monosaccharides on blood products and tissues. Specifically this invention provides a novel family of a3 glycosidases, used for the enzymatic removal of type B antigens from blood group B and AB reactive blood products, and the GaIiIi antigen from non-human animal tissues, thereby converting these to non-immunogenic cells and tissues suitable for transplantation.
摘要:
The present invention concerns a method for treating cancer, including haematological and solid tumors. In an embodiment, the method comprises impairing arginase activity and/or expression in immune cells, in particular T cells of a patient suffering from cancer. Arginase expression may be impaired by mutation (including deletion or truncation) of the arginase encoding gene, by RNA interference or by administration of an arginase inhibitor. In a preferred embodiment, the T cells are modified in the frame of CAR (Chimeric Antigen Receptor) therapy. The invention also provides a method of treatment combining impaired arginase activity with antibody-mediated blockage of negative immune checkpoint regulators (PDL1-PD1 and B7-CTLA4 inhibitory pathways).
