| Outline of Final Research Achievements |
In this study, the HSV-tK gene was firstly transduced into neural stem cells (NSCs) differentiated from human iPS cells using a viral vector. HSV-tk expressing iPS-NSCs were transplanted into human brain tumor model mice, and the effectiveness of this therapy by administration of ganciclovir (GCV) was demonstrated. Next, HSV-tk gene was introduced into iPS by genome editing, but HSV-tk expressing iPS cell line could not be established due to cytotoxicity. Then, Tet-inducible HSV-tk transduced iPS cells were established using gene expression induction system. After induction of differentiation into therapeutic NSCs, these NSCs were transplanted into brain tumor model mice. After administration of GCV with Doxycycline, a remarkable therapeutic effect of this therapy using gene expression induction system was confirmed.
