| Outline of Final Research Achievements |
Regenerative medicine has attracted attention as a new therapeutic method for cerebral infarction, and various clinical trials of stem cell transplantation have been advanced. However, significant therapeutic effects have not been proved, which was largely due to the low engraftment rate of transplanted neural stem cells to cerebral infarction site. Preconditioning of neural stem cells by non-lethal hypoxic stimulation enhances the survival rate of transplanted cells and improves therapeutic efficacies, and is expected to overcome the problems of stem cell therapy. The results of this study suggest that micro RNA has pivotal roles in hypoxic preconditioning of neural stem cells。
