Enucleated Oocytes and Zygotes
The present study was conducted to examine the development of nucLear transplant embryos produced by transplanting nucLei to either oocytes or zygotes in the mouse. Metaphase II oocytes and one-cell zygotes were enucleated and fused with transferred nuclei from late two-, fourand eight-cell stage embryos. Enucleation of metaphase oocytes was achieved using the interference microscope without st...

Effect of Ethanol on Maturation and Development of Immatur Mouse Oocytes
Purpose: To study the effect of ethanol on resumption of meiosis, maturation and development of immature mouse oocytes in vitro. Materials and Methods: Immature oocytes were dissected from ovary of NMRI strain mouse (6-8 weeks old) and divided into control and experimental groups. The absolute ethanol was imposed to oocytes at doses of 0 (Control), 0.05, 0.1, 0.2 and 0.4% (v/v) in maturation c...
متن کاملEffect of Beta-Mercaptoethanol on in Vitro Maturation and Development of Immature Mouse Oocytes
Purpose: This Study evaluated the resumption of meiosis, in vitro maturtion and department of immature mouse oocytes with b- mercaptothanol. Materials and methods: Immature oocytes were recovered from NMRI mouse strain (4-6 weeks) in different 4 experiments groups: the control group, the oocytes were matured in MEM-a+ medium containing + FCS 55%; group 1: the oocytes were matured in MEM- a med...
