Scanning electron microscopy of stellate cells of mammalian adrenal cortex as revealed by NaOH maceration.
After removal of connective tissues by the NaOH maceration method, adrenal gland stellate cells of monkeys, rats and rabbits were studied by scanning electron microscopy. The stellate cells were situated in the perivascular and interstitial spaces and showed an ovoid cell body with numerous round or flat processes. Through these processes they were in contact with other adjacent stellate cells and thus formed a continuous cellular net around capillaries and parenchymal cells. This net, which probably provides a cellular scaffolding for the gland, may also play additional roles such as capillary contraction and nutrition for adjacent parenchymal cells.
