Human mesenchymal stem cells(hMSCs) have tremendous promise for use in a variety of clinical applications.The ability of these cells to self-renew and differentiate into multiple tissues makes them an attractive cell source for a new generation of cell-based regenerative therapies.Encouraging results from clinical trials have also generated growing enthusiasm regarding MSC therapy and related treatment,but gaps remain in understanding MSC tissue repair mechanisms and in clinical strategies for efficient cell delivery and consistent therapeutic outcomes.For these reasons,discoveries from basic research and their implementation in clinical trials are essential to advance MSC therapy from the laboratory bench to the patient’s bedside.
