(A) and (B)The epithelial permeability of DMEM at 37 °C, IEC-6 cells at 37 °C, OGD-preconditioned IEC-6 cells at 37 °C, IEC-6 cells at 32 °C, and OGD-preconditioned IEC-6 cells at 32 °C was assayed by determining transepithelial electrical resistance (TEER). (C) The viability of cortical neurons treated with medium alone at 37 °C was defined as 100%. Measurements were made in triplicate, and each bar represents the mean ± S.D. *P < 0.01, OGD-preconditioned IEC-6 cells+neurons at 37 °C vs. controls; +P < 0.05, OGD-preconditioned IEC-6 cells+neurons at 32 °C.
