Then human iPS cells were implanted into the fertilized eggs, and animal embryos containing human cells were cultivated as animal collecting embryos. Then they were transplanted back into the uterus of experimental mice. Researchers expect fetal mice to have pancreas formed by human iPS cells when they grow up. It is reported that Japanese researchers will also implant human iPS cells in fertilized eggs of cynomolgus monkeys and pigs, but they will not be transplanted to the uterus for the time being. They will only carry out research on iPS cells. In March this year, the Ministry of Science of the Ministry of Culture of Japan revised the relevant regulations to allow the cultivation of human organs in animals, in order to strengthen research on the use of animals to cultivate human organs for transplantation. IPS cells have similar differentiation potential to embryonic stem cells by reprogramming mature somatic cells, but the method is relatively simple and avoids the ethical issues in embryonic stem cell research, which is considered to be of great value in clinical treatment.
