The fibroblast growth factor family: structural and biological properties.


PMID 2491263

Abstract

This article summarizes the structural and biological properties of the family of fibroblast growth factors (FGF). Basic FGF (bFGF) and acidic FGF (aFGF) are the best characterized members of this family. bFGF and aFGF are potent modulators of cell proliferation, motility and differentiation. They are also potent angiogenesis factors in vivo. Some of the important biological characteristics of bFGF and aFGF discussed in the review include the affinity of bFGF and aFGF for heparin, their lack of secretion in culture and their association with extracellular matrix. Recently, several oncogenes, 40-50% homologous in sequence to bFGF and aFGF have been identified. These include int-2, hst, K-fgf and FGF-5. The structural and biological properties of these FGF-related oncogenes are also discussed.
