In biology, the theca of follicle can also refer to the site of androgen production in females. The theca of the spinal cord is called the thecal sac, and intrathecal injections are made there or in the subarachnoid space of the skull. In human embryogenesis, the theca cells form a corpus luteum after a Graafian follicle has expelled its secondary oocyte arrested in second meiosis. 網頁1990年12月1日 · Hormonal Regulation of Thecal Cell Function during Antral Follicle Development in Bovine Ovaries* Endocrinology Oxford Academic The hormonal regulation of thecal cell function was investigated with cells isolated at various stages of antral follicle development.

網頁Thecal cells in culture appear to alter their steroidogenic capacity from an androgen-producing cell to a progesterone-producing cell. Analysis of the developmental regulation of thecal cell function revealed that androgen production and hormone responsiveness were relatively constant in small, medium, and large follicles. 網頁To test the hypothesis that leptin signals metabolic information to the reproductive system in cattle by directly affecting IGF-I-induced ovarian cell function, granulosa and thecal cells from bovine ovarian follicles were cultured for 2 d …
網頁Theca interna cells express receptors for luteinizing hormone (LH) to produce androstenedione, which via a few steps, gives the granulosa the precursor for estrogen manufacturing. After rupture of the mature ovarian follicle, the theca interna cells differentiate into the theca lutein cells of the corpus luteum.
網頁2024年11月29日 · The granulosa and theca cells are a site of action for the gonadotropins and a site for production of steroid hormones ( 22 ). An increase in gonadotropin releasing hormone from the hypothalamus stimulates gonadotropin release from the pituitary, which promotes follicular growth and estrogen (E2) secretion from the ovaries ( 23 ).
