Meiotic and Developmental Competence of Mouse Antral Oocytes1

The equine oocyte: factors affecting meiotic and developmental competence.

There is currently much interest in assisted reproduction techniques in the horse, however, many aspects of oocyte maturation, fertilization, and embryo development in the horse differ from those in other species. Because of the close attachment of the equine oocyte to the follicle wall, scraping of the follicle is the most effective method for oocyte recovery. A notable feature of equine oocyt...

the 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.

P-36: The Effect of Lipoic Acid on Developmental Competence of Cultured Isolated Mouse Preantral Follicles

Background: α-Lipoic acid (LA) is a cofactor in mitochondrial multienzyme complexes and is well-known for its antioxidant properties in both of in vivo and in vitro condition. Materials and Methods: Preantral follicles were isolated from 2 weeks old NMRI mice ovaries. LA at concentrations of 0 and 100 μM was supplemented to culture media (α-MEM medium supplemented with 5% FBS, 100 mlU/ml FSH, 1...

Mouse Oocytes and Embryos Cryotop-vitrification Using Low Concentrated Solutions: Effects on Meiotic Spindle, Genetic Material Array and Developmental Ability

The effect of all-trans retinol on in vitro mouse embryo's developmental competence

BACKGROUND: All-trans retinol is a biological antioxidantscavenging the ROS in the cell culture. OBJECTIVES: This studywas conducted to investigate the effect of all-trans retinol infertilization and culture medium on mouse embryo's developmentalcompetence. METHODS: This study was designed into twoexperiments. In the first experiment, in vitro mature oocytes wereco-cultured with sperm in fertil...
