Hwang and his colleagues claimed to have replaced the nucleus of an unfertilized human egg with the nucleus of an ordinary cell taken from another person, developing stem-cell lines from the resulting embryo that matched the DNA of the person who supplied the ordinary cell. That achievement appeared to take us significantly closer to a world in which patients could be given cell or tissue transplants that their bodies would not reject, because the biological materials, cloned from the patients themselves, would be a perfect match.
黄禹锡及其同事宣称，他们将未受精人卵核替换为从另一个人身上提取的正常细胞核，从而，从由此产生的胚胎上制成了干细胞株，这一胚胎符合提供正常细胞人的NDA。这一成就似乎把我们大为推近到这样一个世界，那就是将来可以对病人进行细胞或组织移植，而病人的身体不会拒绝，因为从病人自身身体克隆而得的生物材料将会完全相符。
