2005年11月24日韩国著名的科学家黄禹锡在首尔(前译为汉城)召开记者会,公开承认他的团队在进行人类胚胎克隆研究时,所用的卵细胞是由其研究队中的两位年轻女性研究人员捐出的,也有卵细胞是买回来的。实际上,自2004年2月黄禹锡在英国《自然》杂志上发表他们成功地从人类克隆胚胎研发出干细胞株后,一直遭受国际学界的一些质疑,比如他的研究员捐出卵细胞、他所属的大学当时并没有设立伦理委员会来审查他的计划是否符合伦理规范、他没有办法提供捐赠者的自愿同意书等等。当时黄禹锡否认了这些指控,但近日与黄禹锡合作的美国科学家宣布解除合作,而原拟与黄禹锡合作成立世界干细胞
November 24, 2005 South Korea's famous scientist Hwang Woo-Sik held a press conference in Seoul (formerly Seoul) to publicly acknowledge his team's use of two young women in their research team in carrying out human embryonic cloning studies Researchers donated, there are also eggs bought. In fact, Hwang has been questioned by international scholars since February 2004 when published in the journal Nature in the United Kingdom for successfully developing stem cell lines from human cloned embryos. For example, his researchers donated egg cells and his university At that time, no ethics committee was set up to examine whether his plan was in line with ethical norms and he had no means to provide voluntary consent of donors. Hwang denied the allegations at that time, but the U.S. scientists who had co-operated with Hwang Yoo-tin recently announced the dissolution of their cooperation and the original attempt was made to establish a world-class stem cell with Hwang
