Expressions of p-Cx43, t-Cx43, and G-CSFR proteins in rabbit myocardium from each group. The expression levels of each protein were determined using immunohistochemistry. Positive staining is shown in brown; the nuclei are stained blue-black. a p-Cx43. b t-Cx43. c G-CSFR. Quantification of expression was performed under high magnification (400×). The black arrows indicate representative enriched areas, but not all areas are indicated by arrows in the images. Data are shown as means ± standard deviations (n = 10/group, except n = 9 in the AG490 group). *P < 0.05, **P < 0.01 vs. Sham group; #P < 0.05, ##P < 0.01 vs. CME group (one-way ANOVA with LSD post-hoc test)
