- Traditionally , somatic nuclear transfer in mammal is completed by micromanipulation . but micromanipulation is evidently damaging to cytoplast cytoskelton , causing the lost of some important factors involved in programming of donor karyoplast , reducing the volume of cytoplasm
传统核移植总效率低，且需要熟练的显微操作技术，所需设备昂贵，限制了核移植的广泛应用；因此作为替代，化学去核应运而生。 - Since the success of dolly , the first cloned sheep with the adult somatic cells as karyoplast donor , new approaches have been developed for nuclear transfer technology . here we describe a handmade cloning method which combines the chemical induced enuleation and zona - free technology in embryo culture . enuleated oocytes were derived by exposing the oocytes to demecolcine and cytoheximide supplemented mdium sequently and its chromosome was depleted to the first polar body
将培养10h的化学去核卵母细胞与供体成纤维细胞融合后lh 、 2h 、 3h ，分别有77 . 6 % 、 70 . 6 % 、 58 . 9 %重构胚的染色质发生凝集，其余胚胎的染色体则处于原核期;而只在融合后3h ， 27 . 9 %重构胚被标记出组装的纺锤体，且其中的同源染色体己经分离。
