Nevertheless all living things have much in common, in their chemical composition, their germinal vesicles, their cellular structure, and their laws of growth and reproduction.
High dose of co-trimoxazole treatment caused significant structural abnormalities and decreases in ovarian quality, including the number of germinal vesicles and metaphase I and metaphase II of rat oocytes.
In vitro culture and maturation of Germinal Vesicle (GV) oocytes is an efficient method to generate mature oocytes.
41) GVBD, germinal vesicle breakdown; MII, metaphase II; IBMX, 3-isobutyl-1-methylxanthine.
maximus from the Eastern Gulf of Mexico, Collins and McBride (2015) observed a diel pattern of oocyte maturation in females: germinal vesicle migration of the vitellogenic oocytes occurs in the late morning-early afternoon preceding spawning day.
The oocyte maturation begins with germinal vesicle migration (GVM, early hydration), going to germinal vesicle breakdown (GVBD, middle hydration) and hydrated oocyte stage (HO, final hydration) when it is previous to spawning (Figure 2e-f).
In fact, supplementation with myoinositol in the IVF technique is positively associated to meiotic progression of mouse germinal vesicle oocytes, enhancing intracellular [Ca2.
Oocyte meiotic process can be observed through the nucleus in the form of phase transformation: Germinal vesicle [GV], germinal vesicle Break Down [GVBD], Metaphase I [MI] to Metaphase n-[M-II].
In vitro maturation and fertilization of goat oocytes vitrified at germinal vesicle stage.
Based on the experimental group, 18 or 36 hr after the onset of cultivation, the maturation status of the oocytes in each group was examined and classified as GV, germinal vesicle breakdown (GVBD) or metaphase II (MII) while MII oocytes were submitted to IVF.
Conversely, nemertean oocytes remain immature with an intact germinal vesicle when treated with calcium-free seawater (CaFSW) (Fig.
