Biochemical characterization of the Arctic char (Salvelinus alpinus) ovarian progestin membrane receptor [PDF]

, 2005
Membrane progestin receptors are involved in oocyte maturation in teleosts. However, the maturation-inducing steroid (MIS) does not appear to be conserved among species and several progestins may fulfill this function.

Cumulus Cell Transcripts Transit to the Bovine Oocyte in Preparation for Maturation

Biology of Reproduction, 2015
So far, the characteristics of a good quality egg have been elusive, similar to the nature of the physiological, cellular, and molecular cues leading to its production both in vivo and in vitro.

Gonadotropin elevation is ootoxic to ovulatory oocytes and inhibits oocyte maturation, and activin decoy receptor ActRIIB:Fc therapeutically restores maturation

Reproductive Biology and Endocrinology
Background Elevated FSH often occurs in women of advanced maternal age (AMA, age ≥ 35) and in infertility patients undergoing controlled ovarian stimulation (COS). There is controversy on whether high endogenous FSH contributes to infertility and whether

Expression profile and gap-junctional transfer of microRNAs in the bovine cumulus-oocyte complex

Frontiers in Cell and Developmental Biology
MicroRNAs (miRNA) are important regulators of oocyte maturation, playing a key role in modulating gene expression both in a temporal- and spatial-specific manner.

Relationship between chromatin configuration and maturation ability of rat oocytes in vitro and in vivo.

PLoS ONE
PurposeEmbryo engineering requires a large number of oocytes, which undergo in vitro maturation (IVM). Understanding how to select the best quality oocytes is key to improving IVM efficiency.
