title: Class II antigenicity of human cartilage: relevance to the use of homologous cartilage graft for reconstructive surgery.
abstract: The presence and distribution of class II transplantation antigens was studied on fresh and Merthiolate-preserved human nasal, tracheal, auricular, and rib cartilage using monoclonal antibodies in an indirect immunoperoxidase method. Substantial class II antigen expression was found on cells of the superficial area of the perichondrium of the nasal, auricle, and tracheal cartilages. In contrast, cartilage tissue lacked cells with detectable class II antigens. Our results indicate that the host response to fresh cartilage graft is induced by class II antigens presented in the perichondrium. A complete disappearance of this class II antigenicity of perichondrium can be achieved by means of an adequate Merthiolate preservation.
