Figure 4

A–C. Representative sections of atherosclerotic plaques after chronic irradiation with 6 Gy using antibodies anti-CD68 (A), α-SMA (B) and MMP-9 (C) D. Mean percentage of total plaque area occupied by CD68- or α-SMA-positive cells. E. Intensity measurement of immunohistochemical staining with anti-MMP9 by HistoQUEST software. Quantitative analysis involved 18 plaques/group. Data are shown as mean ± SEM. Differences were tested with Student's t-test. *P < 0.05; ***P < 0.0001. Bars: 100 μm.
