title: [Role of fibroblast growth factor-2 in tumor angiogenesis].
abstract: Angiogenesis reflects a balance between stimulating and inhibitory factors, among which fibroblast growth factor-2 (FGF-2) and vascular endothelial growth factor (VEGF) play a central role. FGF-2 stimulates endothelial cell growth and migration and enhances angiogenesis, both in vitro and in vivo. FGF-2 binds to a specific receptor (FGF R1) at the surface of endothelial cells. In addition to its extracellular effects, FGF-2 exerts intracellular effects that seem to be independent from tyrosine kinase-type receptors. FGF-2 is produced by several tumor types, including brain tumors, skin tumors, and fibrosarcomas. FGF-2 may play a pivotal role in angiogenesis in these tumors.
