Maturation is complete when the second meiotic division is arrested at metaphase where the egg will await fertilisation. Non-fertilised eggs arrested in the second meiotic metaphase were also observed. In the primordial follicle oocytes reach the dictyate stage of prophase 1, at which point meiotic arrests occurs. Common genomic rearrangements arise through unequal meiotic recombination and result in complex but distinct behavioural and cognitive phenotypes. This would then provide a 'less competent' model for mouse meiotic maturation in vitro. The role of calcium in progesterone-induced meiotic maturation in amphibian oocytes remains unclear. Factors influencing resumption of meiotic maturation and cumulus expansion of porcine oocyte-cumulus cell complexes in vitro. Stage-specific changes in protein phosphorylation accompanying meiotic maturation of mouse oocytes and fertilization of mouse eggs. The resumption of meiotic maturation can be triggered also after the liberation of the oocytes from their follicles in vitro. The c-mos proto-oncogene product is a cytostatic factor responsible for meiotic arrest in vertebrates eggs. In conclusion, somatic cell nuclei are unable to go through meiotic division when introduced into oocyte meiotic cytoplasm, partly due to the abnormal kinetochore distribution. In conclusion, the results of this study suggest a positive paracrine effect of co-cultured cumulus cells on meiotic maturation. It is concluded that careful attention to specific energy substrate supplementation and culture volume is important to optimise spontaneous meiotic maturation in vitro. Regulation of meiotic metaphase by a cytoplasmic maturation promoting factor during mouse oocyte maturation. At first sight, this may indicate a role for the 'elimination chromatin' in the organisation of the second meiotic spindle. Since the meiotic chromosomes in the female perform no crossing-over, tetraploid females are as fertile as diploids. Meiotic recombination break points resolve at high rates at the 5k end of a maize coding sequence. Whether these (or other) chromosome modifications are essential for the initiation and the completion of meiotic maturation remains unknown. Overheating is detrimental to meiotic spindles within in vitro matured human oocytes. Only one previous report is available on pharmacological treatment for meiotic suppression of horse oocytes. Ability to complete meiotic maturation was markedly diminished in oocytes cultured in medium supplemented with verapamil. Although no maturation kinetics studies were carried out, this observation would indicate that meiotic maturation is accelerated after a period of inhibition. Immunoreactive inhibin in follicular fluid is related to meiotic stage of the oocyte during final maturation of the porcine follicle. These examples are from corpora and from sources on the web.
