| 简介 |
The present invention relates to a method for increasing the efficiency of offspring production in producing animals belonging to the family Canidae (canines) by somatic cell nuclear transfer. More specifically, relates to a method for increasing the efficiency of production of cloned canines by a method for cloning canines comprising enucleating the oocyte of a canine to prepare an enucleated oocyte, fusing a nuclear donor cell with the enucleated oocyte to prepare a nuclear transfer embryo and transferring the nuclear transfer embryo into the oviduct of a surrogate mother, wherein the nuclear donor cell is cultured in a medium containing a specific cell cycle synchronization-inducing substance such as roscovitine in the preparation thereof. The method enables to clone canines with high efficiency, and thus can contribute to the development of studies in the fields of veterinary medicine, anthropology and medical science such as the propagation of superior canines, the conservation of rare or nearly extinct canines, xenotransplantation and disease animal models. |
