| Outline of Final Research Achievements |
Cell therapy using iPS cells is attractive for regenerative medicine, cancer, etc., however, a lot of concerns such as rejection and tumor formation after transplantation remain at moment. To solve those issues, we have established the stable cell line of suicide gene-induced human iPSCs by modified method. When neural stem cells (NSCs) derived from suicide gene-induced human iPSCs were transplanted into mouse brain, those cells were alive and survived well, then wiped out by administration of drug. When those NSCs were transplanted into the brain of malignant brain tumor model animals, the tumor volume reduced and transplanted animals survived longer. Those findings suggested that our established human iPSC line might be useful as a therapeutic stem cells for both stroke and tumor.
