The tissue-engineered trachea transplant avoided the need for immunosuppression therapy because the graft was created using the recipient's own cells.1
In this procedure, scientists utilized a donor trachea scaffold that had been stripped of its original cellular components. To repopulate this scaffold, they used mesenchymal stem cells and epithelial cells derived directly from the patient. Because the transplanted tissue was populated with autogeneic (self) cells, the patient's immune system did not recognize the graft as foreign, thereby preventing immune rejection.12
