Epithelial integrity of EC mono- and triple cell co-cultures. TEER in16HBE14o- mono-cultures (A) and triple cell co-cultures (B) before (white bars) and after (black bars) exposure to high dose of DEP (125 μg/ml) or normal medium (control) for 24 h. TEER in mono-cultures was significantly lower after DEP treatment than before addition of DEP (A, *). Data are presented as means ± standard deviation (SD); * p ≤ 0.05. All experiments were independently done in triplicate.
