Fibroblast Growth Factor
Title: Fibroblast Growth Factor
CAS Registry Number: 62031-54-3
Additional Names: FGF
Literature References: Growth stimulatory factor originally isolated from bovine brain and pituitary and found to stimulate DNA synthesis in cultured fibroblast cells. Isoln: D. Gospodarowicz, Nature 249, 123 (1974). Mitogenic effect on cultured cell lines and induction of amphibian limb regeneration in vivo: D. Gospodarowicz et al., Adv. Metab. Disord. 8, 301 (1975). Two closely related forms have been identified, known as basic (bFGF) and acidic (aFGF) fibroblast growth factors, having a total amino acid sequence homology of 55%. Both induce the proliferation and differentiation of a wide variety of cell types, including corneal and vascular endothelial cells, myoblasts, chondrocytes, osteoblasts and glial cells. FGF has neurotrophic and angiogenic activity and may play an important role in the wound healing process. Purification of bFGF from pituitary: D. Gospodarowicz, J. Biol.
