双语趣听精彩世界 第108期:英科学家在动物体内培育出首个完整器官

 　　The Telegraph: British scientists have built a complete and functional¹ organ in a living animal for the first time.

　　British scientists have produced the first working organ by reprogramming cells in a step towards the 'Holy Grail' of being able to grow replacement² organs for humans.

　　In future the technique, so far only tested on mice, could be used to provide replacement organs for people with weakened immune systems and eventually lead on the production of more complex organs for transplant. The technique could be used in humans in ten years.
