Lung, Epithelium, Alveolus - Hyperplasia - Gallery

Image of alveolar epithelial hyperplasia in the lung from a male B6C3F1/N mouse in a chronic study
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.
Image of alveolar epithelial hyperplasia in the lung from a male F344/N rat in a chronic study
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.
Image of alveolar epithelial hyperplasia in the lung from a male F344/N rat in a subchronic study
Lung, Epithelium, Alveolus - Hyperplasia in a male F344/N rat from a subchronic study. Alveolar epithelial hyperplasia secondary to inflammation is associated with numerous alveolar macrophages and minimal hemorrhage.

Lung, Epithelium, Alveolus - Hyperplasia, Atypical from a male F344/N rat in a chronic study. Atypical cells (arrows) are enlarged with enlarged nuclei.
