Abstract
Exposure of cultured rat epididymal preadipocytes to human very low density lipoproteins (VLDL) resulted in the rapid accumulation of large amounts of cellular triglyceride which was accompanied by the appearance of numerous large cellular lipid inclusions. Addition of heparin produced a two-fold stimulation of lipoprotein induced triglyceride accumulation. Supplementation of the growth medium with either low density lipoprotein, oleic acid or artificial triglyceride emulsion did not produce cellular triglyceride levels equivalent to that obtained with VLDL. Fibroblastic cells from rat skin and lung did not accumulate triglycerides when exposed to VLDL and heparin.
