Bone Marrow Mesenchymal Stem Cell Therapy and Related Bone Marrow-Derived Orthobiologic Therapeutics.

Abstract

The purpose of the current article is to review the available literature related to bone marrow-derived mesenchymal stem cell therapy in the management of musculoskeletal pathologies and demonstrate the critical need for additional well-designed clinical studies. In recent years, there has been a rapid increase in interest regarding the use of bone marrow-derived mesenchymal stem cells in the treatment of musculoskeletal injury and disease. The clinical use of BM-MSCs and other forms of stem cell therapy has far outpaced the basic and translational science evidence required to elucidate the potential efficacy of this orthobiologic treatment approach. Early studies have demonstrated potential clinical benefit of utilizing bone marrow-derived mesenchymal stem cell therapy in the management of knee osteoarthritis, focal chondral lesions, shoulder pathology including rotator cuff tears and glenohumeral arthritis, and degenerative disk disease in the spine. To date, most published studies are small case series often lacking a control group or a standardized method of treatment. Bone marrow-derived mesenchymal stem cell therapy is becoming an increasingly common treatment for musculoskeletal injuries and disease. Although early clinical studies have shown promising outcomes, methodological flaws and lack of standardization among trials have limited the conclusions that can be drawn from the existing literature. A better understanding of the underlying mechanism of action and more carefully designed clinical trials will help reveal the efficacy and utility of BM-MSCs as a treatment modality for various orthopedic pathologies.
