Fibroblast Growth Factor Fibroblast Growth Factor (FGF) is one
the most studied growth factor families. They are all protein
growth factors and considered ligands. Originally, only two were
identified FGF-1 and FGF-2, also known as acidic-FGF and basic-
FGF. Since the first discovery, at least twenty more family
members have been identified. FGFs play many important roles
within the body, particularly with the cells. FGFs influene cell
differentiation, migration, and mitogenesis. There have also
been four FGF receptors discovered. These receptors, FGFR1-4,
also play key roles in the body. View Research related to
