Regulation of Mammalian Oocyte Meiosis by Intercellular Communication Within the Ovarian Follicle.
Annual Review of Physiology, 2017 Meiotic progression in mammalian preovulatory follicles is controlled by the granulosa cells around the oocyte. Cyclic GMP (cGMP) generated in the granulosa cells diffuses through gap junctions into the oocyte, maintaining meiotic prophase arrest ...

FEBS Open Bio, EarlyView.The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Follicular fluid content and oocyte quality: from single biochemical markers to metabolomics
Reproductive Biology and Endocrinology, 2009 The assessment of oocyte quality in human in vitro fertilization (IVF) is getting increasing attention from embryologists. Oocyte selection and the identification of the best oocytes, in fact, would help to limit embryo overproduction and to improve the ...

Bulletin of the National Research Centre, 2023 Background The developmental competence of oocyte derived from in vitro maturation (IVM) is significantly lower than those of oocyte matured in vivo. Rapamycin is an immunosuppressive substance and widely used to prolong the survival and preserve the ...

Functional parameters of spermatozoa obtained by a new selection device
FEBS Open Bio, EarlyView.This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.

The Effect of the Follicle Size and Follicle Number Per Ovary on Oocyte Quality of Local Goat
Jurnal Kedokteran Hewan, 2007 This research was aimed to find out the relationship between the diameter of follicle and the different of follicle number on oocyte quality of local goat. The oocyte originated from the ovary was taken from the Slaughterhouse in Banda Aceh.

A novel mechanism of bulk cytoplasmic transport by cortical dynein in Drosophila ovary
eLife, 2022 Cytoplasmic dynein, a major minus-end directed microtubule motor, plays essential roles in eukaryotic cells. Drosophila oocyte growth is mainly dependent on the contribution of cytoplasmic contents from the interconnected sister cells, nurse cells.

Retrieval of Mouse Oocytes [PDF]
Journal of Visualized Experiments, 2007 To date, only a few studies have reported successful manipulations of Peromyscus embryogenesis or reproductive biology. Together with the Peromyscus Genetic Stock Center (http://stkctr.biol.sc.edu), we are characterizing the salient differences needed to develop this system. A primary goal has been to optimize oocyte/early embryo retrieval.
