American biologists for the first time managed to grow a full-fledged artificial kidney and successfully transplant it into the body of the rat. Experts said they developed an original technique, using a diseased kidney as a “model” to assemble it good copy. “If we can adapt it to growing human kidneys, patients who are now waiting suitable donors will be able to get new organs grown from their own cells, ”said Harald Ott of Harvard University.

Work was carried out on rats in the famous scientific center of the USA – Massachusetts General Hospital – a unit of Harvard medical school. “We can talk about a revolutionary breakthrough, since the kidney is a complex, multifunctional structure, “said a leading British specialist in the field of organ cultivation professor Martin Burchil. It is noted that the damaged organ was first treated with chemicals that destroyed old cells and left connective proteins. Then the rat kidney “template” was filled with “blanks” – these are cells kidneys and blood vessels extracted from rat embryo. In the end, all this entrenched inside the “model”, and after a few weeks the template is already turned into a full-fledged organ. According to the results of transplantation, scientists concluded that the rat’s body didn’t reject the kidney, but it worked not as effective as a natural counterpart. According to experts, this could be due to the fact that rat embryonic cells were not mature enough to work in an adult kidney.

Previously, this technique was used to grow the heart. “This technology allows you to use not only any human kidney regardless of their condition, but also of the animal for later transplants to people, “said Berchil. In his opinion, five years later, to 2018 will be the first transplant of such kidneys to people. Wound scientists at Wake Forest University managed to create an artificial ovary. According to his staff, this development may become real salvation for women who have problems with these internal organs. Emmanuel Opara with colleagues created the ovary, taking two types of hormone-producing cells from rats, and by placing them in an algae capsule. Then the capsule was subjected exposure to compounds from the pituitary gland to stimulate hormone production. It turned out that the cells in the capsule can produce hormones in the same volume as healthy ovaries. Rats USA
