In this section, new arsenals for neurological treatment based on an open source are introduced. "Delytact" and "Stemirac" are discussed in this section. These two new arsenals have been accepted as cell and gene therapy products by the Ministry of Health, Labor, and Welfare. "Delytact" is a viral-gene therapy that targets malignant brain tumors, such as malignant gliomas, while "Stemirac" targets against spinal contusion via self-mesenchymal implantation. Both are permitted clinical arsenals in Japan.
