Figure 4: A significant increase of CD68 expression was present only following CCI injury, which was weak after formalin and CFA injection ((a)–(d); Scale bar, 100 μm). CD68 positive cells were colocalized with Iba-1 ((e); Scale bar, 50 μm). Representative bands of Western blot and quantification of Western blot analysis (f) showed increased level of CD68 in CCI group. * as compared with the naïve group, .
