Disclosed herein are methods for generating SC-β cells using chemically defined, completely serum free media, and isolated populations of SC-β cells for use in various applications, such as cell therapy.

Provided herein are, inter alia, methods for preparing a liquid cell culture media that has lesser lot-to-lot analytical variation, increased performance, and has lesser metal ion concentrations compared to a liquid media prepared by traditional methods. Such liquid media may be used for culturing cells, including but not limited to, recombinant cells.

The present invention relates to, inter alia, compositions and methods, including therapeutic alkaline phosphatases that find use in the treatment of disease, such as microbiome-related diseases. In part, the invention provides, in various embodiments, methods of manufacturing therapeutic alkaline phosphatases.

The present invention relates generally to the field of generating fusion proteins to be used in cancer therapy, and more specifically, to nucleotide sequences encoding the fusion proteins, wherein the chimeric fusion proteins comprises at least one targeting moiety and at least one immunomodulatory moiety that counteracts the immune tolerance of cancer cells.

This invention relates to methods for the enrichment of pancreatic progenitor cells from cell populations derived from pluripotent stem cells, induced pluripotent stem cells and embryonic stem cells. Disclosed herein are the markers CD51 and CD177 for the enrichment of pancreatic progenitors and CD275 for the enrichment or depletion of liver progenitors.

In order to improve the efficiency of inducing differentiation of pluripotent stem cells, provided is a method for promoting differentiation of pluripotent stem cells, the method including a step of culturing pluripotent stem cells in a medium, wherein the medium is a medium containing a) an insulin-like growth factor, b) an insulin analogue preparation containing no zinc, c) an insulin analogue preparation containing a low concentration of zinc, or d) a compound exhibiting an insulin-like action.
