Fig 1. Effects of heat stress on TER and on FD4 permeability in IEC-6 cell monolayers.

IEC-6 cells on Transwell membranes were exposed at 42°C for 0, 3, 6 or 12 h. (A) TER values were monitored across cell monolayers at the indicated times. (B) Permeability of FD4 across the cell monolayer was measured. Data are presented as means ± SEM from three independent experiments and differences among mean values were assessed by one-way ANOVA. p<0.05 and *** p<0.001 compared with the control group.
