Figure 5. Interleukin-8 secretion from HCE-2 cells analyzed by ELISA. Columns represent the amount of IL-8 pg/ml (mean±SD).. One-Way ANOVA, followed by Dunnett’s post hoc test, evaluated the statistical differences (n=6, *0.01<p≤0.05, **0.001<p≤0.01, ***p≤0.001, ns=not significant). Experiments were repeated three times.
