The Japanese received permission to cross the human embryo and animal

Scientists have been conducting experiments on breeding various hybrid species. As a rule, this applies to laboratory animals, experiments which is required to receive types with new properties, to test different drugs and so on. The hybridization occurs, as a rule, within the same species. That is, rats of the same species interbreed with rats of a different kind. Much less crossed different types (the most famous example is the mule, a hybrid of donkey and horse). And very rarely experiment with embryos of animals and humans. However, very soon it will be done by Japanese scientists. They even got permission.

Who will output hybrids of animals and humans

For a start, it should be noted that up to March 2019 there was a partial ban on such experiments, however, as you know, he was shot. The first researcher who managed to obtain permission for breeding of hybrids became Japanese hiromitsu is the Executive of Nakuti. He plans to grow human cells in the embryos of mice and rats, and then transplanting these embryos into a surrogate animal for further observation.

It is worth noting that attempts to create such embryos have been undertaken in the past, but the ban was touched, so to speak, “the lives of the embryos”. Scientists were allowed to create hybrid species, but not bring them to birth.

Why create hybrids of humans and animals?

Mr. Nakaguchi says it plans to move slowly and will not try immediately to achieve the birth of a hybrid animal. Initially it plans to grow hybrid mouse embryos to term in 14.5 days, when the organs of the animal, already formed. The same experiments will be carried out on rats, but their hybrids will grow a little longer is 15.5 days. Later, Nakauchi plans to apply for a permit for the cultivation of hybrid embryos in pigs up to 70 days.

We need to act gradually and cautiously, allowing for dialogue with a skeptical public, which is experiencing anxiety and worry, says Tetsuya Ishii, colleague, Nakaguchi researcher of Hokkaido University in Sapporo (Japan). Some experts in the field of bioethics are concerned about the possibility that human cells can go beyond the development of a target body to move in the brain of the developing animal and potentially affect the Central nervous system. But these problems were taken into account in the design of the experiment.

So why is all this necessary? In fact, it sounds the reason is quite logical: the ultimate goal Nakauchi is the production of animals with organs from human cells, which, ultimately, can be transplanted to people. Thus, in the future it will be possible to grow tissue, organs, and possibly a whole system of bodies to get by transplantation to save human lives.
