On lipid droplets in renal interstitial cells

Summary As the result of histochemical studies, it has been shown that the lipid droplets in the interstitial cells of the renal medulla of the rat contain simple saturated and unsaturated lipids. A possible correlation is suggested between the lipid droplets and the biologically active substances of a lipid character (vasodepressor lipid, medullin, and prostaglandin) which have been isolated from the renal medulla during recent years.This work was supported by a grant from the Danish State Research Foundation.
