Abstract
Radioactive vitamin A acetate was stored in specific cells in the mouse adrenal gland. Radioactivity was detected in lipid droplets of fibroblast‐like cells, whose distribution was from the capsule to the medulla. Their population was highest in the cortex. The morphology of these labeled cells was similar to that of vitamin A‐storing cells in other organs of mouse (Yamada and Hirosawa, 1976).Though functions of these cells are obscure, the fact that they are found in organs where metabolic activity of vitamin A is high suggests that they bear some role in the metabolism and storage of the vitamin.
