Lung, Alveolar/Bronchiolar Epithelium - Hyperplasia - Gallery
Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. This low-magnification image shows the distribution of the lesion.
Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. This lesion occurs adjacent to bronchioles and alveolar ducts.
Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study (higher magnification of Figure 2). The majority of the cells are not ciliated, but some are (arrows).
Lung, Alveolar/bronchiolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study. Secondary alveolar epithelial hyperplasia associated with inflammation is present at the bronchiolar-alveolar duct junction.
Lung, Alveolar epithelium - Hyperplasia in a male B6C3F1/N mouse from a chronic study (higher magnification of Figure 4). Large, foamy macrophages, neutrophils, and lymphocytes are associated with the alveolar epithelial hyperplasia.
