Comparison of the intracellular lipids of cultured vascular endothelial cells and fibroblasts.
The lipids of human umbilical vein endothelial cells, calf aortic endothelial cells and foreskin fibroblasts have been compared. Cell cultures were established, and, upon confluency, the lipids were extracted and analyzed with respect to total lipid content, classes of lipids and total lipid fatty acid composition. The total quantity of lipid per milligram protein found in both human umbilical vein endothelium and calf aorta endothelium was similar to that found in fibroblasts grown in similar medium. Both types of endothelium contained the same major neutral lipid classes as fibroblasts, although they contained more phospholipid than did fibroblasts. The fatty acid composition of the three cells examined was influenced by cell type as well as the type of serum in the culture medium.
