齐天大圣一把毫毛“根根能变、应物随心”的广大神通被神通广大的中国科学家变成了现实,他们成功突破了克隆灵长类动物的世界难题——北京时间25日凌晨,克隆猴姐妹“中中”和“华华”的萌照登上了国际权威学术期刊《细胞》的封面。

成功克隆在基因上与人类最接近的灵长类动物,这个重大创新性成果着实令人兴奋。不少闻之者不由得欢呼起来——猴子都能克隆,下一步是不是就能……看来长命百岁不是梦了!

不!“克隆非人灵长类动物的唯一目的是服务人类健康,但科研人员不考虑对人类进行相关研究”,中国科学家坚守科学伦理底线的回答铿锵有力。

神话与科学的分野就在于,神话可以天马行空,科学必须恪守伦理。孙悟空的毫毛想变就变,克隆技术的应用则必须戴上金箍。这个金箍就是伦理。

自绵羊“多利”诞生之日起,围绕克隆技术的伦理争论就从未停止过。到底是该支持治疗性克隆、禁止生殖性克隆,还该全面禁止,众说纷纭。

在这一问题上,我国的态度历来明确:中国政府反对生殖性克隆、支持治疗性克隆。人的生殖性克隆也就是克隆人,违反人类繁衍的自然法则,损害人类作为自然人的尊严,会引起严重的道德、伦理、社会和法律问题。所以,现阶段生殖性克隆绝对不可以应用于人类本身。

同时,生殖性克隆和治疗性克隆的研究高度相关,就隔着一层“窗户纸”。允许治疗性克隆,必须防止有人把这层“窗户纸”捅破。这就需要科研人员严守道德底线,不随意使用“幻化之术”,同时更需严格立法,规范科学研究,把治疗性克隆置于严格监管之下,给孙悟空戴上小花帽,常念紧箍咒。

科学技术上能够做到的,不一定就是应该做的。克隆技术的推进应该是漫长而审慎的,尤其是克隆技术应用于人事关人类未来命运,必须保持高度警惕,以免人类反被自己铸就的科技利剑所伤。

中国突破体细胞克隆猴世界难题 人类重大脑疾病诊治迎来光明前景

中国科学院24日在北京宣布,经过中国科研工作者的不懈努力,2017年11月27日、12月5日,世界上首个体细胞克隆猴“中中”和妹妹“华华”先后诞生,中国因此成为第一个实现了非人灵长类动物体细胞克隆的国家。这一成果将为未来有效治疗脑疾病和中国人口健康领域的重大挑战做出贡献。
