Scientists from the Land of the Rising Sun want to finally make practical use of the world’s latest technologies of genetic modification in living organisms. The first artificial superhuman will be built in Japan.
The research is conducted by Hiromitsu Nakauchi, along with his team of scientists from the University of Tokyo. Some time ago they created the world’s first pig-human chimeras, from which it was possible to take organs for transplantation in humans as part of tests.
However, the ambitions of the Japanese team are much bigger. Scientists want, by means of advanced genetic modifications, not only to create a system of mass production of organs replacement for people and to lay the foundations for eternal life, but also want to create a new species of animals that will have the characteristics and capabilities that have been reserved for humans.
Scientists are experimenting on rats and pigs because they are mammals whose body’s functioning is close to ours, human. The scientific world sees the possibility of creating pig-human chimeras, above all for the needs of transplantation. Such organs are to be perfectly matched to a particular patient, and the recoil risk is practically limited to zero.
The experiments involve injecting a embryo into the pig’s embryo, at the blastocyst stage, the inducible pluripotent stem cells of the patient who are waiting for the transplantation of the organ. Cells are made from somatic cells. In such a pig-human chimera, there are tissues, both animal and human. Only the kidneys that are transplanted are made entirely of the patient’s cells.
Researchers say blood vessels raised from human and porcine cells will not induce organ recoil in patients. The research conducted by Japanese specialists caused a huge wave of criticism in medical circles. Scientists accuse Nakauchi of violating all ethical principles, because the brains of chimeras and their reproductive organs are also formed with the participation of human stem cells, and this is a subject of great controversy.
Nakauchi, however, wants to approach this unrewarding topic from the most ethical and moral side. Therefore, his team will not create and kill embryos for no reason. The research is to be strictly controlled by the University of Tokyo authorities and government bodies. However, the aim of the Japanese is noble, they want to open a new chapter in the history of transplantology, which will be a quick and effective exchange of any organs on request.
