Complete regeneration of epithelium and cartilage tracheal rings occurred after the implantation of decellularized tracheal allografts without immunosuppression. We demonstrate that the decellularized process reduces the allogeneic response to the trachea. Therefore, we believe that the decellularized tracheal allograft is an excellent choice for tracheal replacement. To our knowledge, this is the first study to observe the long-term (1 year) prognosis of this transplanted trachea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
