Lung, Epithelium, Alveolus - Hyperplasia - Gallery

Lung, Epithelium, Alveolus - Hyperplasia in a male B6C3F1/N mouse from a chronic study. There is a small proliferation of alveolar epithelial cells with no inflammation.

Lung, Epithelium, Alveolus - Hyperplasia in a male F344/N rat from a chronic study. There is no change in the normal alveolar architecture in this focus of alveolar epithelial hyperplasia.

Lung, Epithelium, Alveolus - Hyperplasia in a male F344/N rat from a chronic study (higher magnification of Figure 2). The hyperplastic epithelial cells are cuboidal.

Lung, Epithelium, Alveolus - Hyperplasia in a male B6C3F1/N mouse from a chronic study. The hyperplastic epithelial cells line slightly thickened alveolar septa.
