Without a doubt, one of the most serious diseases are those that affect human organs so much that the latter become unable to perform their function. Then you have to resort to transplantology. However, not every transplanted organ will survive due to the fact that a person’s own immune system begins to attack an alien organ. There are many methods that suppress this process, but a group of scientists from the University of California at Davis (USA) suggests to go the other way: to grow whole organs in sheep.
The Guardian writes about the new development, and, according to the authors of the work, the cultivation of human organs in animals in this way can solve the problem of incompatibility. In the course of their work, American scientists use human stem cells, which are introduced into the embryos of sheep at the sites of the laying of certain tissues. Thus, scientists hope that implanted cells can develop into a healthy organ, suitable for transplantation. According to one of the authors of the work, Dr. Pablo Ross,
“To date, even ideally suited organs do not last long, because the immune system constantly attacks them. The only exception is an extremely rare case of transplantation from identical twins. Embryos of sheep are chosen by us not by chance, and their use has a lot of advantages. Firstly, the organs of sheep are easily adopted, which means that we need a smaller number of embryos for the experiment. But the most important thing is that sheep and people have similar in structure lungs and heart. And this is one of the most difficult organs for transplantation. “
Now a team of scientists will observe the embryos within 28 days. This time will be enough to follow the development of organs and see the first results on the formation of hybrid tissues. Depending on the results obtained, the team will adjust its further work on the cultivation of new organs. Many scientists believe that such research is an important step towards the development of transplantology. And how do you think? Speak out about this in ourtelegram chatting!
