Basic Fibroblast growth factor (FGFbasic), also known as bFGF, FGF2, FGF-β or HBGF-2, belongs to the FGF family. FGF-basic is involved in a number of biological processes including embryonic development and differentiation, neuron differentiation, survival, and regeneration, and the proliferation of cells of mesodermal origin and many cells of neuroectodermal, ectodermal, and endodermal origin (PMID 3272178, 3316527). FGF-basic is critical for human embryonic stem cells to remain in an undifferentiated state during cell culture (PMID 15782187).

I tried Your HumanKine FGFbasic-TS in my culture and my cells are very happy. It's an excellent alternative to other FGFs from other companies that have trouble delivering on time their orders.
