Phenotype: granulosa cell gata4 expression absent, abnormal
Note: This phenotype statement describes a gene expression or antibody labeling pattern. Anatomy terms are combined with a gene or antibody and phenotype quality.
EXPRESSION ANATOMY:
Name: granulosa cell
Synonyms: granulosa cells
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.
