Fig 7. Effects of aging and RLX on macrophage accumulation in female ventricles.

Fig 7

A-C. Female. Aged female left ventricles had significant macrophage accumulation (B. 21.47±0.86 macrophages/hpf) compared to young controls (A. 15.57±0.96) and RLX reversed this aged-dependent macrophage accumulation (C. 11.72±1.26). D-F. Male. Male left ventricles showed no change in macrophage accumulation in aging (E. 2.13±0.51) or with RLX treatment (4.88±0.84) compared to young (0.65±0.27) male rats, and had less macrophages than females in each group. G. Quantification of macrophage accumulation. Blue: DAPI; Green: F4/80 macrophage marker; HPF: high power field. Data is reported as mean ± SEM. N.S.: Not significant. 60x magnification. Scale bar: 50 μm.
