Human embryonic stem cells are cloned. Dolly, the cloned sheep was born on July 5th, 1996. 17 years later, human skin cells and an unfertilized donor egg with its DNA removed have been successfully cloned into embryonic stem cells. Researchers from the Oregon Health and Science University have developed a human embryo clone that can be used for regenerative stem cell research. The stem cells can be manipulated to create any other type of cell in the body, which can then be used to replace or repair dysfunctional body parts. While stem cell research using human embryos is controversial in itself, this study cloned a human embryo cell using the somatic cell nuclear transfer method, which is known for being used to clone Dolly. Embryo cloning is the first step toward human cloning, so the study is getting a lot of attention from scientists. Shoukhrat Mitalipov, a reproductive biology specialist at the Oregon Health and Science University who worked on the study said: "While there is much work to be done in developing safe and effective stem cell treatments, we believe this is a significant step forward in developing the cells that could be used in regenerative medicine."
人类胚胎干细胞克隆，克隆羊多莉出生于1996年7月5日，17年后，人类皮肤细胞，并用其DNA取出一个未受精的卵子捐赠已成功地克隆到胚胎干细胞研究的俄勒冈健康科学大学已开发出一种可用于再生的干细胞研究的人类胚胎克隆干细胞可被操纵，以创建任何其他类型的细胞在体内，然后，可以使用以更换或修理不正常的身体部位。使用人类胚胎干细胞研究本身是有争议的，本研究克隆一个人类胚胎细胞，利用体细胞核转移法被用来克隆多莉，这是众所周知的。胚胎克隆是克隆人的第一步，所以研究得到了很多科学家的关注。Shoukhrat米塔利波夫，生殖生物学在俄勒冈健康与科学大学的研究工作的专家说：“虽然有很多工作要做，在开发安全，有效的干细胞治疗，我们相信这是向前发展的细胞，可用于再生医学的一个重大步骤。“
