I heard that some people are working on pigs. This is definitely very interesting/ important direction. For example, pig lives longer than mice, making it a better model to follow up long-term effect of stem cell transplanted (cancer?). Moreover, the development program of pig is closer to human. plus, surgery is also easier than small animals. pig is also more productive than monkey.作者: chenks 时间: 2010-6-28 21:10
