Cellular , hormonal and ionic interactions related to induced and spontaneous oocyte maturation
نویسنده
چکیده
cussed and compared. Spontaneous oocyte nuclear maturation occurs when large ovarian follicles are isolated into seawater and this process is sensitive to the calcium and hydrogen ion concentrations in seawater. In the presence of calcium ions induction of spontaneous oocyte maturation is closely associated with loss of follicle cells from the oocyte. In the absence of calcium ions, follicle cells are also lost from the oocyte, however, spontaneous maturation is inhibited and denuded oocytes do not mature following return to normal seawater. Exposure of isolated follicle cells to calcium ions results in the release of meiosis

O-10: A Marked Animal-Vegetal Polarity in The Localization of Na+,K+-ATPase Activity and Its Down-Regulation Following Progesterone-Induced Maturation
Background: Polarized cells are key to the process of differentiation. Xenopus oocyte is a polarized cell that has complete blue-print to differentiate 3 germ layers following fertilization, as key determinant molecules (Proteins and RNAs) are asymmetrically localized. The objective of this work was to localize Na+, K+-ATPase activity along animal-vegetal axis of polarized Xenopus oocyte and fo...

Background: Cryopreservation of ovaries is an important technique in assisted reproduction technology. Physical forces like hydrostatic pressure have a pivotal role in reproduction systems. Due to changes in intrafollicular pressure during ovulatory process, this study designed to examine the effects of hydrostatic pressure on oocyte maturation and cell death in cumulus cells from cryopreserved...
