Characterization of S100A7 overexpression in HaCaT cells.

<p>(<b>A</b>) S100A7 mRNA levels in HaCaT cells overexpressing S100A7. S100A7 mRNA is normalized to β-actin. The data represent the mean ± SEM of three independent experiments. Statistical significance (**<i>P</i><0.01, ^##<i>P</i><0.01). (<b>B</b>) Immunofluorescence analysis of S100A7 overexpression. Cells were stained for EGFP (green) and anti-S100A7 (red); the nuclei were stained with DAPI (blue). Veh, vehicle; Veh-EGFP, vehicle-EGFP; pso-EGFP, S100A7-EGFP.
