科学家用猪羊培育人体器官引争议 恐造半人半兽

(原标题:半人半兽?科学家用猪羊培育人体器官引争议)

中新网1月12日电据香港《文汇报》12日报道,移植器官供不应求,每年很多患者因为等不及而身亡。美国科学家去年通过基因改造技术,把人类干细胞注入动物胚胎,尝试在猪和羊体内培育人体器官,希望减缓器官短缺,据悉已有至少20只羊或猪被植入改造胚胎。

这一做法引发道德争议,有人批评这些“半人半兽”模糊物种之间的界线,有人更担心胚胎或发育成具人类特征、甚至是人智的生物。

科学家先通过基因工程,去除胚胎某个特定器官并注入人类干细胞,然后把胚胎植入母体,待胚胎成长时,干细胞便会分化成特定器官,填补空缺。类似技术早已应用于白鼠身上,但如今应用于较大型哺乳类动物,被视为在培育人造器官上迈出一大步。

由于胚胎成长及发育需要时间,科学家将要等待数年才能知道这些器官是否适合用作移植。

虽然此技术尚未传入英国,但英国政府预料会于本周公布首份相关指引,宣布有关技术合法。爱丁堡大学罗斯林研究所动物生物科技教授怀特洛认为,英国科研人员会对新技术感兴趣,又指此举“符合商业利益,且可引发健康、具建设性的社会讨论”。

动物权益组织则猛烈批评,称实验把活生生的动物当作培育人类器官的“容器”。评论又指这一技术与普通基因改造不同,实际是在制造新的生物,一旦动物体内发展出人类脑细胞,更可能改变其的思想和行为模式,成“半人半兽”,后果不堪设想。
