The present invention relates generally to glutamine-free cell culture media supplemented with asparagine. The invention further concerns the production of recombinant proteins, such as antibodies, in asparagine-supplemented glutamine-free mammalian cell culture.

Additives and media containing a water-soluble polymer are useful for suspension culture of animal cells, and can suppress the precipitation of medium components such as insulin 5 and the like due to physical stimulation of stirring, shaking, circulation, gas bubbling, or the like in suspension culture of animal cells, and can improve the culture efficiency of animal cells and the quality of cultured cells.

A method of expanding and maintaining human embryonic stem cells (ESCs) in an undifferentiated state by culturing the ESCs in a suspension culture under culturing conditions devoid of substrate adherence is provided. Also provided are a method of deriving ESC lines in the suspension culture and methods of generating lineage-specific cells from ESCs which were expanded in the suspension culture of the present invention.

Methods of expanding tumor infiltrating lymphocytes (TILs) in the presence of an adenosine A2A receptor (A2aR) antagonist, such as vipadenant, CPI-444 (ciforadenant), SCH58261, SYN115, ZM241385, SCH420814, a xanthine superfamily A2aR antagonist, or related adenosine receptor 2A antagonist, and uses of expanded TILs in the treatment of diseases such as cancer are disclosed herein. In addition, therapeutic combinations of TILs and A2aR antagonists, including compositions and uses thereof in the treatment of diseases such as cancer are disclosed herein.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.

Cell culture media are provided herein as are methods of using the media for cell culture and protein production from cells.

Cell culture media are provided herein as are methods of using the media for cell culture and protein production from cells.

Described herein are methods for the production of extracellular vesicles comprising culturing a population of producer cells in single-cell suspension, wherein the cells are cultured in chemically-defined culture medium, wherein the culture medium lacks animal-derived serum and animal-derived components; and obtaining from the cell culture an extracellular vesicle preparation comprising extracellular vesicles. In certain embodiments, the methods comprise perfusion culturing methods, including single-cell perfusion culturing methods and batch-refeed culturing methods. The methods described herein are a significant improvement over the state of the art and fulfills an unmet need in the field of extracellular vesicle manufacturing and quality control.

The invention relates to a method and composition for the cultivation, expansion and production of extracellular vesicles, and the preservation and/or pre-treatment of cells, wherein said composition is a medium or media supplement or a solution comprising pterostilbene or the derivatives thereof, and/or a migration inhibitory factor antagonist and optionally a bivalent cation.

Cultivating a pluripotent stem cell in a medium comprising at least one member selected from the group consisting of ethanolamine, an ethanolamine analog, and a pharmaceutically acceptable salt thereof, and which is substantially free of -mercaptoethanol or contains -mercaptoethanol at a concentration of not more than 9 M, and the like, is effective for the proliferation of a pluripotent stem cell while maintaining an undifferentiated state.
