日本理化学研究所科学家利用老鼠尾巴上的一滴外周血克隆出了一只小鼠。这只雌鼠具有和普通老鼠相同的正常寿命，完全可以生育繁殖后代。由小仓淳郎博士领导的研究小组从一只老鼠的尾部提取血液，分离白血细胞，并且使用细胞核进行了克隆试验。这一方法涉及被称为体细胞核转移技术，也就是把血液细胞或皮肤细胞等成年体细胞的细胞核转移到一个未受孕的已经被去除细胞核的卵子内部。研究人员首次证明使用外周血细胞的细胞核可以克隆小鼠。这些细胞可以在收集后立即用于克隆，而对供体的风险最小，这有助于产生无法用其他辅助生殖手段保存的小鼠品种的遗传拷贝。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
