Figure 5. Inflammatory response in PPARα−/− mice during corneal epithelium repair. Immunofluorescence staining of PMN (A) and positive cell counting (C) shows more positive cells at 12 h post injury and then dramatically decreases in WT mice compared to PPARα^−/− mice. Immunofluorescence staining of CD45 (B) and positive cell counting (D) shows more positive cells at 12 and 24 h post injury and then dramatically decreases in WT mice compared to PPARα^−/− mice. Data are shown as mean ± SD n=6–8, *p<0.05, **p<0.01, ***p<0.001. Scale bars: 50 μm. UN, Uninjured.
