这期新闻有一条挺有趣。似乎是本届世界干细胞高峰会上的一个讨论期间，有观众问谁是当今干细胞研究领域的爱因斯坦以及Steve Jobs。关于谁是干细胞爱因斯坦的回答说目前还找不出一个有爱因斯坦级别的“明星”。关于谁是干细胞界的Steve Jobs，回答说没有人能在自己家的车库里搞出革命性的干细胞产品（与iPhone之类相比）。因为，FDA要管。而Jobs不曾面对这个婆婆。 7 o# A- C2 o c$ @ M s5 q& x& t' p0 s. a
生物医药和生物技术曾被盖茨称为引领下一代产业革命的领域，显然，从完全不同的产业规则上来讲，对公众的“误导”不轻，呵呵。1 t! b3 U& p9 w
