Lost organs can come back in humans, scientists claim

If a person loses any part of his body in an accident, then he has to remain in that condition for the rest of his life. However, now a research has claimed that humans, like salamander creatures, have the 'unused' ability to regrow their lost limbs.Like salamanders, humans have the ability to regenerate parts of their bodies, such as a lost limb, according to a team of researchers.

Research at the MDI Biological Laboratory in Harbour helped experts to conclude that humans have an 'untapped' ability to regrow a lost organ. During the research, the scientists focused on understanding why the axolotl does not form any marks of injury, or does not respond to injury in the same way that rats and other mammals do.

They found in the study that immune cells called macrophages promoted the growth of tissue cells, but caused scarring in the rat.

The research team says that scar formation may be responsible for blocking regeneration in mammals and, in the future, blocking the pathway to the brain could lead to scarring that allows humans to regrow lost limbs. Or can improve overall health.

Dr James Godwin and colleagues compared molecular signaling after injury in axolotl salamanders to that of an adult rat, which has limited regeneration capacity.

Godwin explained that instead of regenerating lost or injured body parts, mammals usually make a scar at the site of injury, which hinders regeneration.

"Our research shows that humans have an untapped potential for regeneration," he said, adding that solving the problem of scar formation could unlock that latent regenerative potential. The research paper on this issue was published in the journal Developmental Dynamics.
