[Allograft antigenicity of human ear cartilage and effect of cell extraction on antigenicity].

Objective: To study the allograft antigenicity of human ear cartilage and the effect of the cell extraction on antigenicity.

Methods: The human ear cartilage was acellular by cell extraction with Triton X-100. Then the cartilage and the acellular cartilage were analyzed by anti-MHC-I immunohistochemical staining, the reaction of the peripheral blood mononuclear(PBM) cells to the cartilage and the acellular cartilage and the migration of the PBM cells toward the cartilage and the acellular cartilage.
