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 s 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.

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.

The present invention is of methods of establishing and propagating human embryonic stem cell lines using feeder cells-free, xeno-free culture systems and stem cells which are capable of being maintained in an undifferentiated, pluripotent and proliferative state in culture which is free of xeno contaminants and feeder 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.

Provided herein are nutrient media formulations and engineered growth factors, and methods thereof, useful for the production of slaughter-free meat.

The present invention relates to animal protein-free cell culture media comprising polyamines and a plant- and/or yeast-derived hydrolysate. The invention also relates to animal protein-free culturing processes, wherein cells can be cultivated, propagated and passaged without adding supplementary animal proteins in the culture medium. These processes are useful in cultivating cells, such as recombinant cells or cells infected with a virus, and for producing biological products by cell culture processes.

This invention relates to a novel cell culture medium and methods to enhance recombinant antibody purity using the cell culture medium disclosed herein. The novel cell culture medium is a self-made feeding medium, which comprises from about 90 nM to about 500 mM cysteine, from about 50 mM to about 500 mM tyrosine, and from about 50 mM to about 300 tryptophan. This invention also relates to a method of growing cell culture using the cell culture medium disclosed herein By controlling the concentration of cysteine in the self-made feed medium as well as the amount and time of adding this feed medium into the cell culture, the purity of antibodies is significantly improved while glycosylation profile and antibody expression level are consistently maintained to guarantee the efficacy of antibodies.

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.

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.

The present invention provides a culture method of cells and/or tissues including culturing cells and/or tissues in a suspended state by using a medium composition wherein indeterminate structures are formed in a liquid medium, the structures are uniformly dispersed in the solution and substantially retain the cells and/or tissues without substantially increasing the viscosity of the solution, thus affording an effect of preventing sedimentation thereof, and the like
