Objectives: In order to treat a rat model of rotator cuff rupture, this work concentrated on the expression of TNMD and RUNX2, followed by rotator cuff repair and secretome-hMSCs.Methods: A total of thirty 10-weeks-old male Sprague–Dawley rats were separated into five groups randomly, RC on week 0, lesion treated with a rotator cuff repair and saline (RC + NaCl group, n = 6) for 2 and 8 weeks, and lesion treated with a rotator cuff repair and secretome-hMSCs (RC + secretome-hMSC group, n = 6) for 2 and 8 weeks. The supraspinatus and infraspinatus muscle–tendon units were obtained for histological and biomechanical investigation at 0, 2 and 8 weeks following injury.Results: The findings showed that, in comparison with the RC + NaCl group, secretome-hMSCs significantly improved tendon repair by upregulating TNMD and RUNX2 expression and histology score.Conclusion: Combining Secretome-hypoxia MSCs with RC healing may help rats with rotator cuff tears. Level of evidence: IV
