title: Transforming growth factor-beta inhibits endothelial cell proliferation.
abstract: Transforming growth factor-beta (TGF-beta) is an inhibitor of the proliferation of bovine aortic endothelial cells in culture. Basal cell growth in serum-containing medium and cell proliferation stimulated by fibroblast growth factor (FGF) are inhibited by TGF-beta in a dose-dependent manner. Half-maximal inhibition occurs at an inhibitor concentration of 0.5-1.0 ng/ml. TGF-beta does not appear to be cytotoxic and cells treated with the inhibitor grow normally after removal of TGF-beta. High concentrations of FGF are ineffective in overcoming TGF-beta-induced inhibition of cell proliferation, suggesting that antagonism of growth factor-induced cell proliferation by TGF-beta is of a noncompetitive nature.
