title: Antiangiogenic properties of fibstatin, an extracellular FGF-2-binding polypeptide.
abstract: By using the two-hybrid system with basic fibroblast growth factor (FGF-2) as bait, we isolated and characterized fibstatin, an endogenous M(r) 29,000 human basement membrane-derived inhibitor of angiogenesis and tumor growth. Fibstatin, a fragment containing the type III domains 12-14 of fibronectin, was produced as a recombinant protein and was shown to inhibit the proliferation, migration, and differentiation of endothelial cells in vitro. Antiangiogenic activity of fibstatin was confirmed in a Matrigel angiogenesis assay in vivo, and electrotransfer of the fibstatin gene into muscle tissue resulted in reduced B16F10 tumor growth. Taken together, these results suggest that fibstatin could act as a powerful molecule for antiangiogenic therapy.
