Figure 1. Level of cytotoxicity in
HCE-2 cells analyzed by MTT assay. Columns represent the
viability of cells (mean±SD. The viability of control cells is
set as 100%. 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.
