Activated oocyte development across the reproductive lifespan: a research article mapping developmental trajectories and regulatory checkpoints that shape follicle progression and longevity.
Key Takeaways
- Lineage tracing shows activated oocytes differ in lifespan with some persisting from early adulthood to reproductive termination.
- Divergence in activated oocyte longevity emerges at the secondary follicle stage and creates a buffering ovarian reserve.
- FURIN regulates activated oocyte metabolic state and modulates follicle growth through the oocyte-secreted factor KITL signaling axis.
