Abstract
The present invention relates to an AG-haESCs in which H19 DMR and IG-DMR are knocked out, a method for preparing the AG-haESCs, and use of the AG-haESCs in constructing a genetically modified semi-cloned animal and a library of a genetically modified semi-cloned animal. The AG-haESCs is capable of obtaining characteristics resembling a round spermatid, and upon injection into an oocyte, a viable SC mouse is stably obtained. The present invention is capable of being effectively used in multi-gene genetic manipulation, advancing the acquisition of animals with multiple genetic modifications.
