follicular atresia การใช้

• A degenerative process called follicular atresia reabsorbs vitellogenic oocytes not spawned.
• In humans, the rate of follicular atresia increases at older ages ( around 38-40 ), for reasons that are not known.
• Fas antigen, a cell surface receptor protein that is expressed on granulosa cells, mediates signals that induce apoptosis by binding Fas ligand and therefore plays an important role in follicular atresia.
