Granulosa cells developing follicles secrete
WebBecause GDF9 is produced by the oocyte of growing follicles, these observations provided the first evidence that the oocyte was controlling the recruitment of theca cells to the developing follicle. Hence, theca cells in the Gdf9 null mice fail to organize around the granulosa cells to form a follicle, and as a consequence, ovarian follicular ... WebWhat do the granulosa cells of developing follicles secrete? A follicle that has two layers of follicular cells is called a primary follicle. These cells continue to hypertrophy and proliferate to form many layers surrounding the oocyte. Eventually these cells become known as ‘granulosa’ cells.
