People learn to grow a limb

American scientists Wistar Institute discovered the mechanism that stimulates the growth of amputated limbs in humans. Helped uncover the mechanism geneticists lizards, which differ in ability to re-grow lost tails or other extremity.

Thanks to studies by geneticists revealed the presence of a particular gene p21 in the body lizards, which blocks existing in the body recovery potential. With a considerable amount of effort, scientists have managed to block the gene, and these experiments eventually produced results. Laboratory rodents were able to restore the badly damaged tissue. While normal mice delayed wound and scar, the experimental mice to form new tissue by the rapid growth of cells.

These experimental results, Professor Ellen Heber-Katu, leading the research team explained that, without a gene found in cells of the body begin to behave like stem, they have the ability to turn into any kind of tissue. According to scientists, the gene p21 in the future may be temporarily blocked and people have a period of treatment, and maybe even get off the gene directly into the wound area.

To avoid potential side effects, to reach off the gene will be using local administration of drugs. This discovery will change the lives of a significant number of people who were left without any limbs, the better.
