Chromosome condensation activity in ovulated metaphase II mouse oocytes assayed by fusion with interphase blastomeres.
Fusion of large and small karyoplasts produced from metaphase II mouse oocytes with interphase blastomeres from 2-cell and 8-cell embryos (volume ratio of partners, 1:1) results in premature chromosome condensation (PCC) of the interphase nucleus in the majority of the fusion products (hybrids). Fused under the same experimental protocol, oocyte-derived cytoplasts also induce PCC of the blastom...
متن کاملAge-Associated Lipidome Changes in Metaphase II Mouse Oocytes
The quality of mammalian oocytes declines with age, which negatively affects fertilization and developmental potential. The aging process often accompanies damages to macromolecules such as proteins, DNA, and lipids. To investigate if aged oocytes display an altered lipidome compared to young oocytes, we performed a global lipidomic analysis between oocytes from 4-week-old and 42 to 50-week-old...
متن کاملActivation of Akt (protein kinase B) stimulates metaphase I to metaphase II transition in bovine oocytes.
In somatic cells, the serine/threonine kinase Akt (or protein kinase B) was shown to contribute to processes linked to cellular growth, cell survival and cell cycle regulation. In contrast to these findings, the function of Akt during the meiosis of mammalian oocytes remains to be investigated. We analysed the phosphorylation pattern and the activity of Akt during meiotic maturation (transition...
متن کاملThe Influence of Meiotic Spindle Configuration by Cysteamine during in vitro Maturation of Mouse Oocytes
Background: The aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. Methods: Pre-mature mice were primed with pregnant mare stimulating gonadotrophin (PMSG) and germinal vesicle (GV) stage oocytes were obtained 48 h after. The oocytes were cultured in tissue culture medium (...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
