Fibroblast growth factor 2 (FGF2) or basic FGF has a broad range of physiological roles including regulation of cell proliferation and differentiation. FGF2 is used to support the maintenance of human embryonic stem cells and proliferation and differentiation of induced pluripotent and mesenchymal stem cells. FGF2 from zebrafish has been used extensively to support the maintenance of human stem cells. (1–3).
