TL;DR: The concentration and duration of SrCl(2) treatment and the presence or absence of CB in activating medium and cumulus cells had marked effects on mouse oocyte activation and development.

TL;DR: The results suggested that the GV0 configuration in porcine oocytes corresponded to the “nonsurrounded nucleolus” pattern in mice and other species, and the in vitro systems currently used were not favorable for oocytes to switch toward ovulation (or final maturation) or atresia.

TL;DR: Cloned goats were produced by NT from cumulus cells and long‐term cultured fetal fibroblast cells to abattoir‐derived oocytes and microsatellite analysis of 10 markers confirmed that all cloned offspring were derived from corresponding donor cells.

TL;DR: The results were consistent with the possibility that the displacement of the FPB was a time‐ and PVS‐dependent process, indicating that PVS would increase with time and its formation and enlargement would facilitate the lateral displacement ofThe degenerating FPB.

TL;DR: Goat oocytes were capable of normal nuclear maturation and activation after temporal arrest by HX, but prolonged exposure to HX induced spontaneous activation, consistent with the possibility that the decline of HX inhibitory effect was not due to Hx depletion but rather due to the negative feedback of the metabolites on its further uptake by oocytes.
