Time course of MALL count and size in the right lung of AIDon mice and wild-type mice.

<p>A, In the left panel, mean density of MALLs in sections per 1 cm² is plotted against mice age in weeks. A solid line with closed symbol and a gray line with open symbol represent AIDon and wild-type mice, respectively. Error bars represent standard errors for data from three mice, except for a wild-type mouse and a 75-week-old AIDon mouse each of which was analyzed singly. Area of a dotted rectangle was enlarged in the right panel. B, Cross-sectional area with individual MALLs plotted. Mean values are indicated by red lines.
