Biologists at Harvard University (USA) declared to the whole world that they created an artificial kidney that can perform all the functions of its natural counterpart. Neoplasm already transplanted into the body of the rat.

According to an article in the scientific journal Nature Medicine, a group of scientists, led by Professor Harald Ott, managed to grow artificial kidney using an original technique that uses the patient's diseased kidneys as a "template" for the assembly of its serviceable copy.

"What is unique in our methodology - we keep the" architecture "of a kidney patient, as a result we can just transplant the new kidney, and connect it to the circulatory and urinary system. If we can adapt it for the cultivation of human kidney patients are now waiting for the right donors will receive new organs grown from their own cells, "- said Harald Ott .

According to the method Ott, damaged organ is first treated with a combination of chemicals that destroy the cells and allowed to framing their connecting proteins. Then, the "template" is filled through the former artery and urinary tract "blanks" kidney cells and blood vessels extracted from embryonic rat. Gradually changing the pressure, temperature and chemical composition of the culture medium, scientists have ensured that most of these cells penetrated the "template" and entrenched in "cells", where previously lived cell rodent. After a few weeks of harvesting has become a full-fledged body, passed through a blood and urine,.

The operation to transplant an artificial kidney in the body of the rat was completed successfully. The body of the animal is not torn the tumor and started using it for other purposes.

However, the artificial organ is not as effective as its natural counterpart. Scientists attribute this to the fact that the rat kidney cells of the embryo were not mature enough for use in adult kidney.
