Clinical studies investigating the role of mesenchymal stem cells in healing of fracture non-unions: a systematic review.

Objectives: To identify and evaluate the effectiveness of mesenchymal stem cells (MSCs) in augmenting healing in fracture non-unions.

Methods: A focused literature search was performed on the PubMed/MEDLINE index using the keywords: "non-union", "mesenchymal stem cells", "bone healing", "MSC", "stem cells", and their MeSH terms. The search was reiterated until the 10th of August 2022.
