"We think this is a very promising treatment that could help patients with severe peripheral artery disease for whom there is now no effective therapy," Dr. Michael Murphy, a researcher at the Indiana Center for Vascular Biology and Medicine as quoted by Forbes.

His research team is using adult stem cells along with progenitor cells, to develop cells may make up the lining of blood vessels. Both the stem cells and progenitor cells are extracted from a patient's bone marrow and then injected into the patient's leg.

Patients who participate in the study will receive one stem cell injection, and then be evaluated over a three months. The patients will then be checked for indicators such as blood vessel growth and wound healing.

Seven patients have already gone through the procedure, and Murphy and his colleagues intend to test the stem cell therapy on three more patients.
