| Outline of Final Research Achievements |
We have reported intravenous administration of bone marrow-derived mesenchymal stem cells (BM-MSCs) reduce the incidence of aortic aneurysm. However, optimal injected cell number, injected interval, timing of administration and optimal cell sources were unknown. In this study, we tried to explore optimal stem cell therapy for aortic aneurysm.
Intravenous administration of BM-MSCs not only prevented growth of aortic aneurysm, but conducted regression of aortic aneurysm. The aortic aneurysm was prevented by every 4 weeks administration of BM-MSC, however, it could not achieve by single administration. The regression of aortic aneurysm was maintained until 2 weeks after administration of BM-MSCs. The administration of BM-MSCs was better for regression of the aortic aneurysm than that of adipocyte-derived MSCs or fibroblast. The administration of allogenic BM-MSCs was effective treatment for aortic aneurysm as same as that of autologous BM-MSCs.
