A novel peptide, derived from the human fibroblast growth factor (bFGF), is identified. The molecule is able to inhibit in vitro the effects of Platelet Derived Growth Factor (PDGF-BB) and basic Fibroblast Growth Factor (bFGF) on primary rat smooth muscle cells (RASMC) and primary bovine endothelial cells (BAEC) The molecule is also able to inhibit in vivo angiogenesis CD1 mice.
