Growth factor gene expression by intimal cells in healing polytetrafluoroethylene grafts.

Abstract excerpt

Vascular smooth muscle cell proliferation resulting in intimal hyperplasia is a major cause of late graft failure. In baboons, healing 60 microns internodal distance polytetrafluoroethylene vascular grafts form an intima composed of proliferating smooth muscle cells with a luminal lining of endothelium. The presence of intimal smooth muscle cell proliferation underneath an intact endothelium, without platelet...
