Fluorescence microscopy images of (a) Arginase-1 (red) CD68 (green) co-immunolabeling and (b) iNOS (red) CD68 (green) coimmunolabeling at a single mesh fiber at 3, 7, and 14 days. DAPI was used to stain cell nuclei. Scale bars represent 50 μm. Cell count image analysis of (c) Arg-1+, Arg-1+ CD68+ cells and (d) iNOS+, iNOS+ CD68+ cells at 3, 7, and 14 days. Bars represent the mean ± SEM. Statistical significance as (*) p < 0.05, (**) p < 0.01, (***) p < 0.001, and (****) p < 0.0001. All other differences are nonsignificant. N = 7.
