This study was undertaken to analyse the time relationships between breakdown of
communication in the cumulus-oocyte complex and reinitiation of meiosis in the oocyte. In …

We have recently reported that the adenylate cyclase activator, forskolin, induces in the rat
ovarian follicle both cAMP accumulation and oocyte maturation. We demonstrate here, on …

The temporal relationship between maturational events in the cumulus oophorus and the
oocyte of adult rats was examined. The time of preovulatory surge of LH was estimated from …

The mammalian oocyte is normally arrested in the dictyate stage of the first meiotic division
and resumes meiosis in vivo in response to the appropriate hormonal signals [Ayalon et al …

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 …

The temporal changes of metabolic coupling between the mouse oocyte and the cumulus
cells which follow hCG injection in vivo and FSH treatment in vitro were studied by …

Prior to ovulation, cell-to-cell communication between the oocyte and the cells of the
cumulus oophorus is terminated (NB Gilula, ML Epstein, and WH Beers, 1978, J. Cell Biol …

Heterologous intercellular communication was determined qualitatively by lucifer yellow dye
transfer and quantitatively by transfer of radiolabeled uridine metabolites and electrical …

We have reported that in vitro treatment with follicle-stimulating hormone (FSH) delays by
about 3 h spontaneous meiotic resumption in cumulus cell-enclosed mouse oocytes. In the …

Cumulus cells are metabolically coupled to the mammalian oocyte via heterologous gap
junctions. One function attributed to the gap junctional communications is the transfer of …
