One of the most important functions of fibroblast growth factor-2 (FGF-2 or bFGF) is the promotion of endothelial cell proliferation and the physical organization of endothelial cells into tube-like structures, thus promoting angiogenesis. FGF-2 is a more potent angiogenic factor than VEGF or PDGF (platelet-derived growth factor); however, it is less potent than FGF-1. FGF2 has been used to induce artificial gyrification of the mouse brain. Adult neurogenesis within the hippocampus e.g. depends greatly on FGF2.
