Cumulus Cells (CC) vs Mural Granulosa Cells (MGC) Cumulus cells surround the oocyte. They provide nutrients to the oocyte and influence the development of the oocyte in a paracrine fashion. Mural granulosa cells line the follicular wall and surround the fluid-filled antrum. The oocyte secretes factors that determine the functional differences between CCs and MGGs. CCs primarily support growth and development of the ooc…
