American scientists have proposed an alternative method to avoid rejection by the body incompatible transplant organs . If earlier during such operations used suppressants immunity , Now doctors are hoping that from them will be abandoned in favor of Use stem cells . The tests of the new method have been carried out by experts under the direction of a scientist from Memorial Hospital of Chicago Joseph Leventhal. Journal of Science Translational Medicine has already shared information about the new development.

To date, the medicine widely used agents that suppress the immune system, which allows for prevention rejection   donor organ. Patients passed through transplantation , We have to take these drugs for life. In connection with the reception of these drugs often occurs many side effects such as diabetes   and arterial hypertension , for example. Therefore, experts and began an active search for drug eliminates the immunosuppressive therapy.

To participate in the new study, Dr. Leventhal and his colleagues selected patients who soon had to be transplanted kidney is not a suitable recipient on immunological parameters. Together with the authorities of study participants were implanted hematopoietic stem cells donors. It is from these cells and formation of all blood cells, including immune. Scientists have tried this way to modify the recipient's immune system and prevent organ rejection of the kidney. As a result of the experience of more than half of the patients were able to give up drugs. The researchers first used the stem cells of the donor to conduct kidney transplants inappropriate. According to them, in the future, this technique can be used for transplantation of other organs of immunologically incompatible.
