胚胎干细胞如此让人激动是因为它的天然功能就是分化成身体所有的细胞。
Why people are so excited about embryonic stem cells is because in nature they become all the cells of the body.
从人胚胎生殖嵴、肠系膜中消化分离的原始生殖细胞，将其接种在人子宫内膜成纤维细胞饲养层上传代培养。
PGC from genital ridge and mesenterium of human embryo was incubated on fibroblast feeder layers for subculture.
而用胚胎干细胞进行潜在的医学研究则更是道德错误，因为即使这胚胎只有几个细胞甚至一个细胞，它仍有机会发育成一个人。
And using these cells in potentially lifesaving research is morally wrong because even if that embryo was only a few cells or just one cell, it has the potential to be a human being.
因为从前没有人使用胚胎干细胞或者从干细胞中获得的细胞用于人自身，FDA会非常慎重。
Because no one has used embryonic stem cells, or the cells derived from these stem cells, in people before, the FDA was particularly cautious.
由于动物和动物胚胎随着时间变得更加复杂了，这些细胞和细胞之间的相互作用也越来越让人印象深刻。
As animals, and hence animal embryos, complexified over time, these cell-to-cell interactions have become increasingly impressive.
研究者已经成功的从自然死亡的胚胎当中培育出了一个人胚胎干细胞系。
Researchers have succeeded in developing a human embryonic stem-cell line from an embryo that had died naturally.
人造胚胎实验一直备受争议，因为从一个早期胚胎中提取干细胞后，胚胎就会被摧毁，一些人认为这等同于扼杀生命。
Such experiments are controversial because when cells are extracted from an early-stage human embryo, it destroys the embryo, which some people believe is equivalent to taking a life.
