Research progress of in vitro maturation of Beagle dog oocytes / 中国实验动物学报

ABSTRACT

Sufficient embryos are needed for the preservation of Beagle dogs germplasm resources and the prepara-tion of gene?modified human disease animal models. Up to now, the induced ovulation technique has no effect on dogs,it is hard to obtain mature oocytes in vivo, although the scientists try a lot in many aspects, but still could not make a break?through. The in vitro maturation rate is too low to support the preservation of germplasm resources, application in gene?modified disease models and biomedical research. Aiming to provide useful information on breakthrough in dog oocytes mat?uration, this review will summarize the effect of different age and reproductive stage,different morphology and size of the oo?cytes and lipid droplet on the in vitro maturation of dog oocytes.
