| Definition: | A supporting cell for the developing female gamete in the ovary of mammals. They develop from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the mammalian oocyte in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the ovum in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors. |
