Figure 3: Sample histology images corresponding to a lung lobe slice of a mouse 17 days after instillation. (a) Mosaic acquired at 1.25x magnification. Scale bar represents 1000 microns length. (b) Zoomed area acquired at 10x. Scale bar represents 100 microns length. The mosaic (a) shows heterogeneous distribution of airspace enlargement. In the zoomed area (b), the left portion corresponds to normal alveolar tissue and the right shows the typical airspace enlargement found in emphysema.
