Germinal vesicle definition of germinal vesicle by Medical dictionary

An oocyte , oöcyte, or ovocyte is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in a female fetus in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then … See more Cytoplasm Oocytes are rich in cytoplasm, which contains yolk granules to nourish the cell early in development. Nucleus During the primary … See more Because the fate of an oocyte is to become fertilized and ultimately grow into a fully functioning organism, it must be ready to regulate … See more The spermatozoon that fertilizes an oocyte will contribute its pronucleus, the other half of the zygotic genome. In some species, the spermatozoon will also contribute a centriole, … See more • Cortical granule • Cryoconservation of animal genetic resources • Folliculogenesis • Oocyte maturation inhibitor See more Female mammals and birds are born possessing all the oocytes needed for future ovulations, and these oocytes are arrested at the prophase I stage of meiosis. In humans, as an … See more • Nondisjunction—a failure of proper homolog separation in meiosis I, or sister chromatid separation in meiosis II can lead to aneuploidy, in which the oocyte has the wrong number of chromosomes, for example 22,X or 24,X.

Effect of caffeine on meiotic maturation of porcine oocytes

WebJan 1, 2013 · Just before spawning in sea stars, these messengers lead to germinal vesicle and follicular envelope breakdown (GVBD and FEBD) and to meiosis of primary oocytes (Shirai and Walker, 1988). GSS is a small molecule produced by neuro-epithelial cells of the radial nerves on the oral surface of the sea star. WebIt is still one of the unresolved issues if germinal vesicle stage (GV) oocytes can be successfully cryopreserved for fertility preservation and matured in vitro without damage after warming.
