From: Ingraft chimerism in lung transplantation - a study in a porcine model of obliterative bronchiolitis
Destruction of airway epithelium (A) and obliteration of the bronchial lumen (B), and the positive staining for Y chromosomes in the epithelium (C) and in the bronchial wall (D). The study groups were non-immunosuppressed, inadequately immunosuppressed, or adequately immunosuppressed. Epithelial destruction, luminal obliteration, and positive staining for Y chromosomes were graded on a scale from 0-3. The number of assessed bronchi in each group and on each assessment point was 6.6. ± 1.1 for histological samples and 7.1. ± 1.1 for FISH.
