Activin A

Activin A is a TGFβ family growth factor used frequently for the maintenance of pluripotency in induced pluripotent stem cell (iPSC) and embryonic stem cell (ESC) culture. Activin A is also used in many stem cell differentiation protocols, including for directed differentiation into endoderm lineages such as hepatocyte and pancreatic cells. This protein has been extensively validated for highly reproducible stem cell culture. Qkine founder, Marko Hyvönen, developed the protocol for making high purity activin A and this protein is used at the Cambridge Stem Cell Institute.
