Granulosa Cells: Hormones, Function & Anatomy - Cleveland Clinic

網頁Rat granulosa cells respond to transforming growth factor-beta (TGF beta) with increases in DNA synthesis and FSH-stimulated aromatase activity. To determine if the cells surrounding the granulosa cells generate TGF beta-like activity, which influences the growth and differentiation of granulosa cells, we cultured rat ovarian thecal/interstitial cells under … 網頁By contrast, granulosa cells cultured with theca cells were convex, and formed multilayer sheets. Theca cells cultured alone were thin, flat, and spindle-shaped. Theca cells cultured with granulosa cells were also spindle-shaped; however, they appeared convex and more densely packed when compared with theca cells cultured alone. 網頁The thecal gland differentiates from stromal cells during the life span of the follicle [ 2] and in a number of species survives until its eventual atretic transformation into a small island of steroidogenic cells in the ovarian stroma [ 3 ].

網頁1987年8月1日 · Ovarian thecal cells in culture were found to synthesize and secrete transforming growth factor-β (TGFβ). A component in thecal cell-conditioned medium was immunologically similar to TGFβ, as assessed with a RIA, and inhibited specific binding of TGFβ to its cell surface receptors. 網頁Interstitial cells are formed from thecal cells that persist following follicular atresia and they remain responsive to LH stimulation and produce androstenedione. It is common to see …

The theca folliculi comprise a layer of the ovarian follicles. They appear as the follicles become secondary follicles. The theca are divided into two layers, the theca interna and the theca externa. Theca cells are a group of endocrine cells in the ovary made up of connective tissue surrounding the follicle.
