New Method Could Regrow Human Limbs
A salamander’s limb is unique in the world of vertebrates in that it can regrow from a stump after an amputation. An adult salamander can regenerate a lost arm or leg this way over and over again; regardless of how many times the part is amputated. If such animals which are not that different from their human counterparts , can have the ability to regenerate their body parts, then why not humans?


Humans though have this tendency to regrow body parts but this ability diminishes with age and finally disappears. . Researchers have found that by bathing the stumps of tadpoles’ lost tails in a sodium ion solution for one hour, they can stimulate the growth of a new, fully functional, tail. Tufts researchers believe that the same flood of sodium ions to human injuries could result in the regrowth of limbs far more effectively than stem cells, the next-best answer.
The sodium ion treatment is non-invasive, requiring no gene therapy, and can even be administered after the wound has healed over. Before now, therapies like this one needed to be administered before the injury was sustained, making them terribly impractical. But this method more or less opens up the gateways that allow bodies to regenerate severed limbs, no matter how old the injured person is. The method is particularly useful on spinal cord injuries, a notoriously difficult type of injury to heal.
