Oocyte ageing is a complex of processes that occur when matured in vitro oocytes are, after reaching the metaphase II stage, exposed to further in vitro culture. Aged oocytes remaining at the metaphas...
The oocytes (experiment 1) were harvested by one of the four collection techniques (slicing, puncture, aspiration I and aspiration II) and the total number and the number of each grade of oocytes were...
N,N,N’,N’-tetrakis-(2-Pyridylmethyl) ethylenediamine (TPEN) is a heavy metal chelator with high affinity for zinc. TPEN causes important responses in mammalian eggs. For example, these eggs are arrest...
Ca2+ signaling induced at fertilization, also known as oscillations, is essential in mammalian eggs to initiate early embryonic development. The generation of the oscillations relies on optimization o...
Somatic cell nuclear transfer (SCNT) has generally demonstrated that a differentiated cell can convert into a undifferentiated or pluripotent state. In the SCNT experiment, nuclear reprogramming is in...
This study was conducted to investigate the effects of Trichostatin A (TSA) on cumulus expansion during mouse oocyte maturation. TSA treatment inhibited cumulus expansion and significantly reduced the...
The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups ...
In the antral follicle phase, several layers of cumulus cells surround the oocyte and play an important support and regulation role in oocyte development and maturation via intercellular communication...
Female germ cell meiotic divisions are typically asymmetric, giving rise to two daughter cells with different sizes. Spindle movements including spindle migration from the oocyte center to the cortex ...
It has been recently shown that expression of the LH receptor (LHR) in cumulus cells is related with FSH-induced meiotic resumption of mouse cumulus enclosed oocytes (CEOs). However, to date, it is st...
期刊信息 篇名 Oscillatory change of SR-protein kinase activities during oocyte maturation meiosis in fish 语种 英文 撰写或编译 撰写 作者 Yang,Z.A.,Cao,D.,Gui,J.F. 第一作者单位 中国科学院水生生物研究所 刊物名称 Progress on Natural Sciences 页面...
期刊信息 篇名 Comparative Investigation on Spindle Behavior and MPF Activity Changes During Oocyte Maturation between Gynogenetic and Amphimictic Crucian Carp 语种 英文 撰写或编译 撰写 作者 YANG,Z.-A.,LI,Q.-H.,WANG,Y.-F...
期刊信息 篇名 Intra-oocyte localization of MAD2 and its relationship with kinetochores, microtubules, and chromosomes in rat oocytes during meiosis. 语种 英文 撰写或编译 作者 Zhang D et al 第一作者单位 刊物名称 Biol Reprod 页面 2...
Considerable attention has been focused on the cloning of mammalian embryos, as a consequence of poor development, in order to enhance the application of genetic engineering. Experiments were conducte...
Carbohydrate-protein interactions are known to be important in gamete interactions. Several evidence indicated that a fucose-containing sulfated polysaccharide fucoidan was potential inhibitor of fert...
