Figure 5. Macrophage polarization at day 7 after implantation. (A) Representative F4/80 and iNOS immunofluorescence staining of macrophages infiltrated
in scaffolds; viewed with 200× magnification; scale bar = 50 μm. (B) Representative F4/80 and Arg1 immunofluorescence staining of macrophages
infiltrated in scaffolds; viewed with 200× magnification; scale bar = 50 μm. (C) Quantitative analysis of iNOS intensity in scaffolds with different stiffness
by one-way ANOVA (n = 3, **P < 0.01, ***P < 0.001, ****P < 0.0001, ns: no significance). Notes: S1, low stiffness; S2, medium stiffness; S3, high stiffness.
