Sertoli cells (sustentacular cells) Cells that line the seminiferous tubules in the testis. Named after Italian histologist Enrico Sertoli (1842–1910), Sertoli cells protect the spermatids and convey nutrients to both the developing and mature spermatozoa. They also produce a hormone, inhibin, which can inhibit follicle-stimulating hormone and thereby regulate production of spermatozoa.
