AhRR/EGFP expression in the skin.
(a) Immunofluorescence analysis of frozen sections of dorsal skin of WT, AhRRE/+ and AhRRE/E mice counterstained with DAPI (bars: 200 μm). (b) Flow cytometry of single cell suspensions from epidermis (upper panel) and dermis (middle and lower panel) of either MHCII+ (left) or MHCII− cells (right) (n = 4). Shown are the percentage of EGFP+ cells and the mean fluorescence index (MFI) as indicated. Data are shown as mean ± s.e.m. and significance was determined by one way ANOVA corrected for multiple comparisons by the Sidak method *p < 0.05, **p < 0.01, ***p < 0.001 (WT vs AhRRE/+ or AhRRE/E mice).
