| Outline of Final Research Achievements |
In experimental studies, erythropoietin (EPO) receptor was expressed in mesenchymal stem cells (MSC), and proliferation of MSC was enhanced by adding the EPO in cultured MSC. EPO enhanced angiogenesis partly through activating local MSC in skeletal muscle in ischemic limb. In vivo study of mouse limb ischemia, EPO treated MSC injection group improved limb ischemia significantly more than MSC injection group, but implanted cells have not been survived until chronic stage.
In clinical studies, after approval from the committee of clinical research of human stem cells in the Ministry of Health, Labour and Welfare, study titled “Implantation of erythropoietin-cultured bone marrow stromal cell in patients with intractable peripheral artery disease” has been started, and performed in 2 patients (UMIN ID: UMIN000013820).
