(a) Fluorescence microscopy images of F4/80 CD68, F4/80 CD11b, and CD68 CD11b co-immunolabeled tissue cross-sections at a single mesh fiber at 7 days (additional days can be seen in Supporting Information, Figures 1–3). DAPI was used to stain cell nuclei. Scale bars represent 50 μm. Cell counts of (b) F4/80+, CD68+, and CD11b+ cells and (c) F4/80+ CD68+, F4/80+ CD11b+, and CD68+ CD11b+ cells surrounding single mesh fibers 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.
