Fig. 2

Coexpression of p63 with KRT5 and KRT14 in the healthy human lung. Sections from healthy human lungs (6 donors) were co-stained either for KRT5 (green) and p63 (red) (a left; b left), or KRT14 (red) and p63 (green) (a right; b right) and counterstained with DAPI (blue). One representative picture, with the corresponding high magnification panel, is shown for each staining, for the conducting (a) and distal (b) healthy airways. Arrow: KRT5^-p63⁺ cell. Full bars = 500 μm. Scattered bars = 100 μm
