Web11 de abr. de 2024 · Oocytes also promote primordial follicle growth and activation by expressing different regulatory factors (e.g., GDF9 [54, 55], BMP15 , etc.). In the present study, the mRNA expressions of oocyte marker genes (Figlα, Nobox) and follicle-promoting gene GDF9 were significantly increased in all dose and full-term groups. Web16 de jul. de 2024 · Oocytes mature in a specialized fluid-filled sac, the ovarian follicle, which provides signals needed for meiosis and germ cell growth. Methods have been developed to generate functional oocytes from pluripotent stem cell–derived primordial germ cell–like cells (PGCLCs) when placed in culture with embryonic ovarian somatic cells.

The follicle cells are tightly attached to the oocyte , making it extremely difficult to see the follicle layer and separate it from the oocyte (Fig. 3).To loosen the attachment of the … WebFour studies reported on the main result of live birth rate. It is uncertain whether follicular flushing has an impact on live birth rate compared with aspiration alone. This suggests that if a live birth rate of approximately 30% is seen with aspiration alone, the equivalent live birth rate with follicular flushing lies between 20% and 39%.
WebThe oocyte itself impacts the function of the surrounding somatic cells during all stages of follicular development and thus is the central player in the follicle. By releasing GDF9, the oocyte in primary follicles organizes the stromal precursor cells to form the theca cell layer. 116,117 In preovulatory follicles, GDF9, BMP15, and FGF8 ...
