Abstract:
PDGF is one of the principal mitogens for cultured cells of mesenchymal origin. Apart from aggregated platelets PDGF can be secreted by a number of cells. There is a striking homology between the amino-acid sequence of PDGF and that of a transforming protein of simian-sarcoma virus. PDGF is an important chemotactic protein for cells implicated in wound healing. Furthermore, recent publications suggest a possible role in the pathogenesis of several diseases. This article summarizes studies and recent findings on the structure, biology, and functional role of PDGF.
