title: Atrial natriuretic factor inhibits proliferation of vascular smooth muscle cells stimulated by platelet-derived growth factor.
abstract: The effect of atrial natriuretic factor (Isoleucine-ANF 101-126) on basal and platelet-derived growth factor (PDGF)-stimulated proliferation of rat aortic vascular smooth muscle cells (VSMC) was assessed by microscopy and measurement of incorporation of tritiated thymidine by cells cultured with or without addition of PDGF in the presence of various concentrations (10(-8)-10(-6) molar) of ANF. ANF had little effect on proliferation of cells grown in media supplemented with 2% fetal calf serum (FCS) alone but exhibited clear dose-related inhibition of PDGF-stimulated thymidine incorporation.
