| Outline of Final Research Achievements |
Regenerative therapy has been prospected for new treatment also for cerebral infarction. In this study, we researched the effect of our original endothelial progenitor cells with low aldehyde dehydrogenase (Alde-Low EPC) for cerebral infarction in the rat models.The results was follow; 1.Injection of Alde-Low EPC made the volume of cerebral infarction smaller.2.Alde-Low EPC accumulated in infarction area and showed their effect. 3.Also after 14 days of infarction, we confirmed the effect of Alde-Low EPC for cerebral infarction. More studies which reveal the mechanism of Alde-Low EPC function in cerebral infarction is needed. However, we confirmed that Alde-Low EPC accumulated and effected within 24 hours and their effects continued also after 2 weeks. But we could not find the optimal way for clinical use of these cells. In the next step, we will investigate about mesenchymal stem cells which can be extracted from patients’ fat tissue in the same way in this study.
