| Outline of Final Research Achievements |
We investigated the novel tissue material for airway repair. Pig trachea was decellularised by detergent - enzymatic method treatment into extracellular matrix (ECM) which was confirmed non-antigenicity. Patch material made from this ECM was applied as xenotransplant tissue graft to repair air way defect made on dog’s cervical trachea. ECM patch graft derived from pig was incorporated in heterologous host of dog without immunosuppression and air way defect was restored successfully. On the other hand, applying cytokines such as erythropoietin, G-CSF did not improve epithelialization on the ECM graft, which needs to be investigated further.
