Rapid purification and activity of apolipoprotein C1 on the proliferation of bovine vascular endothelial cells in vitro.
The growth-promoting activity of human high-density lipoproteins (HDL) and of their apolipoprotein components on bovine vascular endothelial cells in vitro has been compared. When maintained on plastic culture dishes and exposed to medium containing lipoprotein-deficient serum and fibroblast growth factor, these cells do not proliferate. Addition of either HDL or the total HDL apolipoproteins induces significant cell proliferation. Apolipoprotein C1, purified by chromatography on the ion-exchanger resin Polybuffer exchanger 94, has an effect on the cell growth similar to that of the total apolipoproteins of HDL.
