The cytoplasm is pale eosinophilic and contains large amount of lipid droplets which appear as numerous vacuoles and so these cells are called spongiocytes).īy EM: the cells show the ultrastructural features of steroid secreting cells i.e.The cells are large polyhedral with large, pale spherical nuclei.The cords are one or two cells thick and are separated longitudinally.The cells are arranged into long straight cords, perpendicular to the capsule.It is the middle and the largest layer of the cortex, forming 65% – 80 % of the cortex.Function: the cells secrete mineralocorticoids, mainly aldosterone. sER, mitochondria with tubular cristae, and few lipid droplets. The cells are columnar or pyramidal in shape with dense nuclei and slightly vacuolated eosinophilic cytoplasm.īy EM: the cells show the ultrastructural features of steroid secreting cells i.e.The cells are arranged in closely-packed arched clusters surrounded by fenestrated blood capillaries. ![]() It lies immediately under the connective tissue capsule, forming 15% of the cortex. ![]()
