American biologists for the first time succeeded in growing high-grade artificial kidney and successfully transplanted it into the body of the rat. Experts have said that developed a novel technique that uses a kidney infection as a "model" to build her a working copy.
"If we can adapt it for the cultivation of human kidney, patients who are now waiting for a suitable donor can receive new organs grown from their own cells," — said Harald Ott at Harvard University.
Work was carried out on rats at the famed Research Center USA — Massachusetts General Hospital — Harvard Medical School Division. "You can talk about revolutionary breakthrough, because the kidney is a complex, multi-functional structure," — said the UK's leading specialist in the field of cultivation of Professor Martin Birch.
It is noted that the first affected organ has been treated with chemicals that destroyed the old cells and left coupling proteins. Then the "template" rat kidney was filled with "blanks" — a kidney cells and blood vessels, extracted from rat embryos. In the end, it all entrenched in the "model", and after a few weeks of the template has already turned into a full body.
According to the results of transplantation, scientists concluded that the body is not torn the rat kidney, but it did not work as effectively as the natural counterpart. According to experts, this could be due to the fact that the rat embryo cells were not mature enough to work in the adult kidney.
Previously, such a method was used for the cultivation of the heart. "This technology not only allows the use of any human kidney, regardless of their condition, but also for subsequent transplantation of animal people", — said Burch. According to him, five years to 2018 will be the first kidney transplant such people.
Rana scientists from the University of Veyk Forest managed to create an artificial ovary. According to his staff, this development can be a real salvation for women who have problems with these internal organs. Emmanuel Opara and his colleagues created the ovary in rats taking two types of cells that produce hormones, and placing them in a capsule from algae. The capsule is then were exposed to the compounds of the pituitary gland to stimulate the production of hormones. It was found that the cells in the capsule can produce hormones to the same extent as healthy ovaries.
