大陸與法國科學家合作育成中期體細胞複製牛
Posted on Monday, October 22 @ 02:14:16 CST by allen

(中央社台北二十一日電)中國大陸與法國科學家合作,以細胞週期同步方法改進和使用損傷切除術,在法國培育出世界上第一頭中期體細胞複製牛。這頭複製牛出生已近三個月,一切理化指標正常。
         新華社今天報導,這頭小牛出生時適逢北京申奧成功,因此命名為「奧運2008」。
         參與研究的科學家指出,在奧運2008出生以前,世界上的體細胞複製牛都是以休眠細胞或生長期的細胞生產,這些細胞時期的細胞核移植到去核卵細胞中,其細胞週期和卵細胞的細胞週期並不相同。世界上一些從事複製牛研究的實驗室,長期以來都試圖用中期體細胞複製牛,但都沒有成功。
         研究人員表示,這項技術將提高動物複製的效率,對促進複製技術研究有重大意義。901021
