Abstract

To determine the possible beneficial effects of a synthetic mechano-growth factor E peptide (MGF-C25E) on the healing of rat Achilles tendon. A significantly increased Achilles functional index was found in the MGF-C25E-treated tendons relative to the saline-treated tendons. Macroscopic observation showed that the repair of MGF-C25E-treated (1000ng/ml) tendons was superior to that of the saline-treated tendons. The mean value of the stiffness of the repaired tendons was significantly increased in the MGF-C25E-treated (1000ng/ml) tendons relative to the saline-treated tendons. Moreover, histological analysis provided evidence of tissue remodeling and cell alignment. MGF-C25E plays an important role in promoting healing of injured rat tendon and could be used as a potential therapeutic factor for tendon repair.
