器官移植是医学上的重大进展,可以挽救许多人的生命。然而由于等待做移植手术的病人很多,而可供移植的器官又很有限,颇使手段高明的外科医生有巧妇难为无米之炊的感叹。所以科学家们不得不另做打算了,他们开始在为人类服务了几千年的猪身上打起了主意,看它们能否再为人类作出更大的贡献。 Organ transplantation is a major medical advance that can save the lives of many people. However, due to the large number of patients awaiting transplant surgery and the limited number of organs available for transplantation, surgeons who are skilled in their methods have the slightest impression that they can not make mistakes. So the scientists had to make another move, and they started to think about whether they could make even greater contributions to humankind by starting to work on pigs serving thousands of years for humankind.
