Figure 2. Arginase inhibition reduces histological changes in diabetic eNOS+/+; but not eNOS−/− mice.

Figure 2

Sections were stained with PAS and images were taken with 100x (oil) objective with a total magnification of 1000x. Images are representative of 4–8 mice in each group. Semiquantitative scores (0–4+) were assigned based on the masked readings, where 0 represents no lesion, and 1, 2, 3, and 4+ represent mesangial matrix expansion or sclerosis, involving ≤25, 25 to 50, 50 to 75, or >75% of the glomerular tuft area, respectively.
