Endothelial Regulation of Vascular Repair: Role of bFGF in Paracrine Pathways.

Vascular repair following injury is mediated by both endothelial and smooth muscle cells often through paracrine pathways. Basic fibroblast growth factor (bFGF) is present at sites of vascular injury. The role of bFGF in regulating reendothelialization through an effect on centrosome redistribution in cell migration is discussed. The role of bFGF in neointimal formation, especially as it relates to smooth muscle cell proliferation, is reviewed. It is concluded that bFGF appears to be an important agent regulating the early responses of the artery wall to injury.
