Mesenchymal Stem Cells Injections in Traumatology and Orthopaedics: Common Practice or Still a Promising Area with Many Uncertainties?

MSC injections represent a growing area of research in traumatology and orthopaedics. However, the results of only a small proportion of clinical trials and systematic reviews are published in peer-reviewed journals, which most likely does not allow practitioners to form a full judgement on the effi...

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 emerge...
