WebAfter rupture of the theca layers and basal lamina during ovulation, theca cells invade into granulosa cell layers as well as vascular and immune cells, resulting in the formation of … WebAdult granulosa cell tumor. A low-grade malignant, sex cord-stromal tumor with a variable number of fibroblasts and theca cells. A variety of growth patterns occur and are often admixed. Adult granulosa cell tumor accounts for about 1% of all ovarian tumors.

Cell culture of granulosa cells can be performed in vitro. Plating density (number of cells per volume of culture medium) plays a critical role for the differentiation. A lower plating density makes granulosa cells exhibit estrogen production, while a higher plating density makes them appear as progesterone producing theca lutein cells. WebGranulosa cells, their precursors, or their final differentiation stages are critical components of the ovary that nurture germ cells, sustain oocyte maturation, provide the hormonal …
WebIn contrast to granulosa and theca cells cultured alone, cells in coculture seemed to possess morphological and functional characteristics more similar to those of cells in the growing follicular wall in vivo. Therefore, we speculate that interactions between these two types of follicular cells is essential in the maintenance of original ...

WebNov 1, 2024 · Granulosa cells in the sex cords produce sex steroids and several peptides needed for folliculogenesis and ovulation. They also give rise to granulosa theca cell tumors (GCT), which form about 5 percent of ovarian neoplasms and are the commonest sex cord-stromal tumors of the ovary (70 percent). WebApr 12, 2024 · These results suggest that adiponectin might exert inhibitory effects on the GnRH and LH. Furthermore, the presence of AdipoR1 and AdipoR2 has been detected …
WebA granulosa-theca cell co-culture experiment showed that theca cell proliferation can be stimulated and steroid hormone secretion can be increased by the presence of granulosa cells. [9,10] In addition, granulosa cells are involved in the differentiation and acquisition of LH responsiveness in stromal cells of the ovarian cortex. [11]
WebThe granulosa cells become granulosa-lutein cells (large cells), and the theca cells are transformed into theca-lutein cells (small cells) (see Fig. 17-15). 74 The so-called K cells, scattered throughout the corpus luteum, are believed to be macrophages.
