S100 protein">S100 immunostain A sustentacular cell is a type of cell primarily associated with structural support, they can be found in various tissues. * Sustentacular cells of the
olfactory epithelium The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 9 cm2 (3 centimetres by 3 centimetres) and lies on the roof of the nasal cavity about 7 cm above and beh ...
(also called supporting cells) have been shown to be involved in the phagocytosis of dead neurons, odorant transformation and xenobiotic metabolism. * One type of sustentacular cell is the Sertoli cell, in the testicle. It is located in the walls of the seminiferous tubules and supplies nutrients to sperm. They are responsible for the differentiation of spermatids, the maintenance of the Blood–testis barrier, blood-testis barrier, and the secretion of Activin and inhibin, inhibin, androgen-binding protein and Anti-Müllerian hormone, Mullerian-inhibiting factor. * The organ of Corti in the inner ear and taste buds also contain sustentacular cells. * Another type of sustentacular cell is found with glomus cells of the carotid body, carotid and aortic body, aortic bodies. * About 40% of carcinoids have a scattering of sustentacular cells, which stain positive for S100 protein, S-100.
