Increased S100A9 expression in K5+/LBR+ keratinocytes.

<p>A-G. Relative qPCR analysis of keratinocytes from week-13 K5-/LBR- (blue) and K5+/LBR+ (red) mice (<i>n</i> = 3 per group). (H) Analysis of keratinocyte proliferation, using Ki67 (red), and DNA-stained nuclei (blue) in paw epidermis of week-8 K5-/LBR- (blue) and K5+/LBR+ (red), (<i>n</i> = 3 per group). (I) No significant differences were observed between K5-/LBR- (blue) and K5+/LBR+ mice (red), (<i>n</i> = 3 per group). Error bars indicate SEM (* <i>p</i><0.05). Scale bar indicates 20 μm.
