| Outline of Final Research Achievements |
This project aimed to create cell-based therapy toward hemophilia. Basic concept of this project is to proliferate patient's own cells with the genetic modification using viral vectors. Hepatocytes and blood outgrowth endothelial cells (BOECs) were used. For hepatocyte proliferation, we isolated hemophilic hepatocytes from factor IX-knockout mice which were then transplanted into uPA/SCID mouse livers. After the transplantation, the hemophilic hepatocytes had been actively proliferated to fully reconstitute uPA/SICD mouse livers. Injecting AAV vectors into the uPA/SCID mice resulted in high level of FIX gene transduction to the reconstituted hemophilic hepatocytes within the liver. The genetically-modified hemophilic hepatocytes were subsequently recovered, followed by their transplantation back into the hemophilic individuals. The present study also utilized blood outgrowth endothelial cells established from factor IX-knockout mice for FIX gene transduction.
