Cell viability of bEECs induced by LPS

Cells were incubated with different concentrations (1, 10, 30, 50, and 100 µg/ml) of LPS for 3, 6, 9, 12, and 18 h. Cell viability was significantly reduced by 30 µg/ml of LPS at 12 h (^* P<0.05). Data represent the mean±SEM of three independent experiments. ^* P<0.05, ^** P<0.01 vs. the control (Con) group
