Mammalian follicles are constituted of a complex structure composed of several layers of granulosa cells surrounding the oocyte and of theca cells that reside beneath its basement membrane. During folliculogenesis, granulosa cells separate into two anatomically and functionally distinct sub-types; the mural...
Cumulus cells (CCs) are a highly specialized cell type that surround the mammalian oocyte from antrum formation to the early stages of embryo development in the oviduct. During this period of close vicinity, CCs maintain paracrine and cell-to-cell communications with the oocyte. The increasing ...

Cumulus cells directly surround oocyte to form cumulus oocyte complex (COC). Oocyte secreted factors act on cumulus cells to regulate the specific functions. Since oocytes have less glycolytic activity, the energy sources, such as piruvate or amino acid, are transferred from cumulus cells to oocyt...
The bi-directional communication between the oocyte and the surrounding cumulus cells (CCs) is crucial for the acquisition of oocyte competence. We investigated the transcriptomic profile of human CCs isolated from mature and immature oocytes under stimu

The present study compared the efficiency of somatic cell nuclear transfer (SCNT) using porcine oocytes that were denuded of their cumulus cells at different maturation time. In pre-denuded group, the cumulus cells from cumulus-oocyte complexes (COCs) were removed at 29 hr post in vitro maturati...
Abstract. Follicular somatic cells (mural granulosa cells and cumulus cells) and the oocyte communicate through paracrine interactions and through direct g
pig oocyteMammalian oocytes grow and undergo meiosis within ovarian follicles. Oocytes are arrested at the first meiotic prophase, being controlled or influenced by follicular somatic cells. Under the influence of gonadotropins, immature oocytes resume meiosis. During meiotic progression, some cytoplasmic ...
