Nuclear transplantation egg, production method of parthenogenesis embryo and parthenogenesis mammal

摘要

This invention, the nuclear transplantation egg which 2 sets it possesses the half genome of ovum origin of the mammal, the parthenogenesis embryo, designates that production method of the parthenogenesis mammal is offered as purpose. Acquired gene decoration is received with about spermatogenesis retreating/quitting in the method of producing the nuclear transplantation egg where (1) after introducing the ng ovum into the GV period egg which is pited, external it matures cultures this invention and, moves to MII period and the process which is made the 1st nuclear transplantation egg, (2) it removes MII period chromosome from the said 1st nuclear transplantation egg, another MII period egg (the fg ovum) introduces and consists of the process which is made the 2nd nuclear transplantation egg, possesses the haploid genome set of ng ovum origin and the haploid genome set of fg ovum origin, as a ng ovum or a fg ovum,It features that the ovum which the imprint gene deficiency is done is used, the nuclear transplantation egg, the parthenogenesis embryo, it is production method of the parthenogenesis mammal.
