Stem cell scientists had what first appeared to be an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in the bone marrow, can give rise to bone, fat and muscle tissue, and have been used in hundreds of clinical trials for tissue repair.

Uses range from tissue protection in heart attack and stroke to immune modification in multiple sclerosis and diabetes. Unfortunately, the results of these trials have been underwhelming. One challenge is that these stem cells don’t stick around in the body long enough to benefit the patient.
