MIT Technology Review reports that in 2015 , about 20 attempts were made to get chimaeras pig-human, and sheep – human . No scientific work has been published so far, and there have been no reports of the successful creation of animals with Human tissues. It is clear why there is such "secrecy". Pay attention to the image made by Hiromitsu Nakauchi with colleagues at the University of Tokyo. From left to right: an ordinary mouse, a mouse with rat cells, a rat with mouse cells, and an ordinary rat. Experiments with chimera’s organisms combine both genetic engineering and stem cell biology. It is not enough just to implant pluripotent cells in the embryo of an animal, because in this case an organism with catastrophic disorders in its development can turn out. "Research workers" usually "turn off" genes in embryos in such a way that they will not be able to form specific tissues. In this case, stem cells take on the task of making the missing organ, no different from Human, which makes it suitable for transplantation. According to cardiologist Daniel Garry , the first tests of this method were carried out in his laboratory. The researchers designed pigs that lacked some skeletal muscles and vessels. Such animals would not be viable, but the researchers implanted stem cells in the embryos from another pig embryo. The results made such impression on the US armed forces that they gave Garry $1.4 million grant for the cultivation of human hearts in pigs. The scientist was going to continue his studies, despite the NIH moratorium ,
