Mixed allogeneic chimerism prevents obstructive airway disease in a rat heterotopic tracheal transplant model.

Abstract

Mixed allogeneic chimerism induces donor-specific tolerance and prevents development of the characteristic fibroproliferative obstructive lesion of bronchiolitis obliterans in a rat heterotopic tracheal transplant model. Excellent preservation of tracheal structure and morphology was achieved across major and minor histocompatibility barriers.
