Abstract: The present study evaluated the effects of in vitro maturation (IVM) on the proteome of cumulus–oocyte complexes (COCs) from ewes. Extracted COC proteins were analyzed by LC‐MS/MS. Differences in protein abundances (p read more here.

Abstract: This study aimed to evaluate the effects of donor age on lipid metabolism during in vitro maturation (IVM) of pigs cumulus‐oocyte complexes (COCs). We evaluated transcript levels of genes, the percentage of ooplasm occupied by… read more here.

Abstract: PurposeWe hypothesized that the chemokine SDF1/CXCR4 system was present in feline cumulus-oocyte complexes (COCs) and that COCs cultured with SDF1 would directly upregulate gene expression in the ovulatory cascade.MethodsOvaries (n = 50) were obtained from adult domestic… read more here.

Abstract: Oocyte in vitro maturation can be improved by mimicking the intra-follicular environment. Oocyte, cumulus cells, granulosa cells, and circulating factors act as meiotic regulators in follicles and maintain oocyte in the meiotic phase until oocyte… read more here.
