According to the reports published by Global Science Nature, the Japanese government will be the first to support a research project using animals to cultivate human organs. Hiromitsu Nakauchi, a biologist at the University of Tokyo in Japan and Stanford University in the United States. He plans to implant human induced pluripotent stem cells (iPS cells) into mouse and rat embryos. Then implant the embryos into experimental animals. Nakauchi’s goal is to develop human organs that we can use for transplant surgery.
Before Japan banned the growth of animal embryos containing human cells for more than 14 days. A lsoprohibited the transplantation of these embryos into the surrogate uterus. However, in March of this year, the Ministry of Education, Culture, Sports, Science and Technology of the People’s Republic of China established new regulations. Which allows human organs to be cultivated in animals. Nakauchi’s pilot program was approved only due to to this new regulation . Nakauchi said he will slowly advance the trial by first culturing hybrid mice and rat embryos to 14.5 and 15.5 days, respectively. And then he will apply to breed hybrid embryos in pigs for up to 70 days.
