Meiotic maturation in cultured bovine oocytes is accompanied by remodeling of the cumulus cell cytoskeleton

Article Abstract:

Researchers used laser scanning confocal and ordinary fluorescence microscopy to examine the connection between the realignment of the cumulus cell cytoskeleton and meiotic progression in bovine cumulus oocyte complexes (COCs) developed in vitro. Bovine oocyte maturation in culture was found to include alterations of the cumulus cell cytoskeleton that may control the emergence, development and consummation of oocyte maturation.

Regulation of meiotic maturation in the mammalian oocyte: interplay between exogenous cues and the microtubule cytoskeleton

Article Abstract:

Regulation of meiosis in mammalian oocytes occurs through intrinsic and extrisic factors. These include meiotic inhibiting factors from the follicular cells, gonadotrophins, cyclin, maturation promoting factors and chromosomal reorganization processes. These regulatory processes are essential to oocyte maturation for entry into the succeeding stages of fertilization.

Association of p34cdc2 and cyclin B1 during meiotic maturation in porcine oocytes

Article Abstract:

The protein kinase p34cdc2 is produced in the G2 meiotic phase in pig oocytes but is not associated with its cyclin B subunit until the first metaphase (MI). The p34cdc2-cyclin B complex continues increasing throughout the second metaphase (MII). In oocytes from non-mammalian species, the p34cdc2-cyclin B complex is present during the GV stage.
