體細胞核移植
體細胞核移植（Somatic cell nuclear transfer，簡稱：SCNT），又稱體細胞克隆，是遺傳學及發育生物學實驗之中一種使用體細胞和卵細胞培育胚胎的常用技術手段。該技術提取去核卵母細胞，並把供體體細胞核移入卵母細胞中。體細胞核移植技術被應用於臨床治療及克隆技術中。世界上第一隻克隆哺乳動物多利羊即是依靠體細胞核移植技術誕生。2018年1月，中國科學院神經科學研究所非人靈長類平台的研究團隊宣布成功通過體細胞核移植技術克隆出兩隻食蟹猴中中、華華。[1]
介紹
細胞核移植技術，就是將供體細胞核移入除去核的卵母細胞中，使後者不經過精子穿透等有性過程即無性繁殖即可被激活、分裂並發育成新個體，使得核供體的基因得到完全複製。[2]1996年世界上第一個使用該技術克隆的動物多利羊誕生。[3]
