Research advances in mesenchymal stem cells and related therapies for rotator cuff tendon-to-bone healing.

Rotator cuff tears (RCTs) are a prevalent cause of shoulder dysfunction, with postoperative retearing remaining a significant challenge due to poor tendon-to-bone healing. Mesenchymal stem cells (MSCs), owing to their multipotency, immunomodulatory properties, and diverse tissue sources, have emerged as a promising therapeutic strategy. Current approaches include direct MSC implantation, MSC-laden scaffolds for structural support, and utilization of MSC-derived conditioned medium (CM) or exosomes to enhance regeneration.
