Culprit for Age-related Decline in Muscle Healing Uncovered

These two photographs show how treatment with the binding-protein GDNF repairs aged muscle stem cells to support robust muscle regeneration. The image on the left shows small muscle fibers (red shapes with blue nuclei inside), which were made by old muscle stem cells. The image on the right shows increased muscle fiber size and muscle stem cell numbers (indicated by green dots) due to GDNF treatment. Credit: Liangji Li
