And as you're thinking about these two guys sequencing a human genome in 2000 and the Public Project sequencing the human genome in 2000, then you don't hear a lot, until you hear about an experiment last year in China, where they take skin cells from this mouse, put four chemicals on it, turn those skin cells into stem cells, let the stem cells grow and create a full copy of that mouse.
如同大家所知道的那样 这两位在2000年进行人类基因组测序 还有2000年的公开项目——人类基因组计划 之后我们就很少听到相关的信息了 直到去年大家听说在中国的一个实验 实验者从老鼠皮肤上取出细胞 加入四种化学试剂 将皮肤细胞转变为干细胞 让干细胞生长 从而创造了那只老鼠的一个完全复制品
