cumulus cells

Cumulus cells are specialized granulosa cells surrounding and nourishing the oocyte. These cells surround the fully-grown oocyte to form a cumulus-oocyte complex (abbr. COC). The terms cumulus oophorus cells, cumulus granulosa cells, cumulus oophorous granulosa cells, granulosa-cumulus cells are used to make a distinction between these cells and the other functionally different subpopulation of granulosa cells at the wall of the Graafian follicle (see: granulosa cells).

Cumulus cells provide key products for the acquisition of developmental competence and differ from granulosa cells ... ... ... ...
