Heparin-like glycosaminoglycans influence growth and phenotype of human arterial smooth muscle cells in vitro. I. Evidence for reversible binding and inactivation of the platelet-derived growth factor by heparin.

Abstract excerpt

We have investigated the effects of interactions between growth factors and heparin-like glycosaminoglycans on untransformed human arterial smooth muscle cells (hASMC) in vitro. The results indicate that heparin in the presence of serum mitogens prevents the cells from entering the S phase of the cell cycle by binding and inactivating reversibly some serum mitogen(s). Our results suggest that platelet-derived...
