Research Advances on Somatic Cell Nuclear Transfer in Yanbian Yellow Cattle

Bovine somatic cell nuclear transfer (SCNT) is a sophisticated technique system,including oocyte maturation,donor cell preparation and oocytes microscopic operation,fusion,activation and culture.Although the birth of cloning cattle has been reported recently,the efficiency of somatic cell cloning has remained lowly.In order to establish the optimization somatic cell nuclear transfer system of Yanbian Yellow cattle,this review summarized only from 6 main aspects mentioned above in this field.
