In the US, medicine for the first time in the history of medicine transplanted a person at once two kidney pigs. According to TASS, American Journal of Transplantation writes about this.
last fall, scientists first transferred to a pig kidney for the first time, and now the first successful transplant operation of a person at once two kidneys grown in the body of pigs. For this experiment, scientists needed the resolution of the relatives of a 57-year-old man who fell into someone and donated their bodies for the benefit of science.
This body scientists have used to understand whether the kidneys will be able to work in the human body. The fact is that the efficiency of the kidney work and the probability of the appearance of failures in their work is greatly dependent on the pressure in the blood vessels. In humans, this figure is significantly higher than that of pigs, therefore, doctors fear that the pig’s kidney transplantation will receive damage even with 100 percent immune compatibility of the organs. Genetics were removed or replaced on human analogs of ten sections of DNA pigs associated with blood coagulation, the growth of cells and the work of the “His own” system. As a result, the transplant organs became not only “invisible” for immunity, but also acquired compatibility with blood systems of media of all types of blood.
Arriving several such pigs, scientists removed their kidneys and implanted them to the patient. Both organs got along and in the first half an hour after the transplant began to purify blood from toxins. In the next three days of observation, Jamie Lok from Alabama University in Birmingham did not recorded any evidence that inside pork kidneys had bleeding and other failures that are potentially associated with high pressure in the human circulatory system.
Doctors hope that due to such transplantation it will be possible to save the lives of several hundred thousand patients who die due to the lack of suitable donors for kidney transplantation.
