Collagen-Derived Dipeptide Pro-Hyp Administration Accelerates Muscle Regenerative Healing Accompanied by Less Scarring after Wounding on the Abdominal Wall in Mice

Pro-Hyp administration induced many myogenically differentiated cells, including myogenin-positive myoblasts and myoglobin-positive myocytes, to migrate in the granulation tissue, while scar tissue decreased, indicating that Pro-Hyp administration accelerated muscle regenerative healing accompanied by less scarring after wounding on the abdominal wall.
