In most mammals, the oocyte in the Graafian follicle is surrounded by tightly packed layers of
cumulus cells, forming the cumulus–oocyte complex. During the preovulatory period …

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 …

The process of cumulus expansion is a current topic of interest for in vitro production of
embryos. In the present study, we examined the components of cumulus expansion …

Communication between the oocyte and its somatic cells has been shown to be important in
oocyte development. Here we examined how the oocyte may be involved in bovine cumulus …

Reproductive biotechnologies are a dynamically developing discipline of farm animal
breeding. Their progress depends on a sufficient quantity of quality oocytes useful for …

The timing of the reduction of cumulus cell-oocyte coupling was correlated with oocyte
meiotic maturation and the expansion (mucification) of the cumulus oophorus using …

Oocyte maturation is a key issue of current animal biotechnology. This study was designed
to examine the morphodynamics of the cumulus-oocyte association during oocyte …

The aim of the present study was to clarify interactions between oocytes and cumulus cells
(CCs) on the level of cumulus expansion and oocyte maturation during IVM of cumulus …

The function that cumulus cells play during oocyte maturation ie, in keeping the oocyte
under arrest, in participating in the induction of meiotic resumption and in supporting …

Mammalian oocyte maturation and cumulus expansion are hormone-induced
contemporaneous processes that involve changes in cumulus cell shape and in the …
