FGF-8a
Fibroblast growth factor 8a (FGF-8a) is a member of the FGF family and plays a key role in the regulation of embryogenesis, cellular proliferation, differentiation, and migration. FGF8a is often used for the differentiation of induced pluripotent stem cells, embryonic stem cells, and neural stem cells.
