Rebuilding worn muscles with age, one day could be as simple as taking a pill, because scientists believe they may have found the secret to restore youth to the muscles.

The key would be a protein that is responsible for sending chemical signals to reactivate the stem cells that can repair muscles, once discovered now expect a drug can boost muscle development, which would slow the aging process.

In the U.S. and European researchers are studying the ability of stem cells to repair damaged tissue and build muscle, having discovered that as we age, the chemical messages that tell stem cells work, they become weaker.

As a result, the body takes longer to repair the damage, and their findings, published in the journal EMBO Molecular Medicine, paving the way for developing a pill that would increase those messages and thus strengthening the muscles.

The researchers worked on thigh muscles in young men, aged between 21 and 24 and in men aged between 68 and 74.

Reaching this conclusion: “Our study shows that the capacity of human muscle, can be maintained and repaired by muscle stem cells that can restore youthful vigor, given the proper combination of biochemical signals.
