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.

The present disclosure pertains to compositions comprising anti-VEGF proteins and methods for producing such compositions.

The present disclosure pertains to methods for producing aflibercept from a host cell cultured in a chemically defined medium (CDM) including purification of aflibercept, wherein aflibercept following purification includes aflibercept variants that have at least one oxidized amino acid residue selected from the group consisting of tryptophan, histidine and a combination thereof.

The present invention provides a basal cell culture medium and a feed medium with novel amino acid ratios and/or iron choline citrate as iron carrier that result in improved performance of mammalian cell culture processes, such as CHO cultivation and protein production processes, in particular in increased product titer (e.g. of monoclonal antibodies). Also provided are methods for culturing mammalian cells and producing a protein of interest using said basal cell culture medium and optionally feed medium. The invention also provides for a medium platform that comprises (i) the basal cell culture medium and (ii) the feed medium.

The invention describes improved methods and compositions for producing a recombinant protein, e.g., an antibody, in mammalian cell culture. In addition, the invention provides improved cell culture media, including improved production media, feed solutions, and combination feeds, which may be used to improve protein productivity in mammalian cell culture.

In accordance with the present invention, CHO cells expressing a recombinant polypeptide of interest are grown in media where the amino acids, vitamins, phosphate, lipids and/or antioxidant optimization is utilized to manipulate and/or control the protein quality attributes of the polypeptides. Polypeptides expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical compositions.

The present invention relates to the method for mass production of mesenchymal stem cell-derived proteins including various growth factors and cytokines, a mesenchymal stem cell conditioned medium containing a large amount of protein and produced by the above production method, cosmetic composition and pharmaceutical composition including the above conditioned medium for skin regeneration, anti-wrinkle, alopecia treatment, prevention of hair loss and promotion of hair growth. The method for mass production of the mesenchymal stem cell-derived protein of the present invention can greatly increase the amount of various growth factors and proteins which are known to be not expressed from mesenchymal stem cells or expressed only in very small amounts by the existing culture method, and the mesenchymal stem cell conditioned medium prepared by the above method contains a large amount of various kinds of cytokines and growth factors so that it has the excellent effect on skin regeneration, wrinkle improvement, prevention of hair loss, alopecia treatment and hair growth promotion.

The present disclosure pertains to compositions comprising anti-VEGF proteins.

The present disclosure pertains to compositions comprising anti-VEGF proteins and methods for producing such compositions.

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