Not surprisingly, given its huge potential, teams of scientists have been mobilized almost everywhere for embryonic stem cell research. The race has become all the more dramatic since the leading researcher, the US, dropped out, owing to the influence of religion on politics (although the state of California has decided not to miss out, and recently approved a $3 billion subsidy for embryonic stem cell research).
鉴于其巨大的潜力，几乎世界各地的科学家都投身于胚胎干细胞的研究也就并不奇怪了。美国由于宗教对政治的影响而退出（尽管加利福尼亚州已经决定不退出，并且最近批准30亿美元补贴用于胚胎干细胞研究），从此以后，这一竞赛变得更为富有戏剧性。
