Stanford researchers find culprit in aging muscles that heal poorly
...re fibroblasts is that the healing muscle had more scar tissue, also known as fibrosis. "That says something about how cells decide who they're going to be. Even if they start off knowing they're supposed to be a muscle cell, they can change," said Rando.

...dy, the healed tears appeared as highly reflective scar tissue. "We are successfully performing dynamic sonography in muscular trauma and our players have benefited tremendously in the management and follow-up of muscle tears," said Dr. Nath.
