Effect of EP2 receptor agonist and antagonist on TER of Caco-2 epithelial monolayer.

<p>Caco-2 monolayer that reached confluence on transwell plate was exposed with either 10 µM of Butaprost (EP2 specific agonist) or 50 µM of AH6809 (EP2 antagonist) on the apical side and TER (Ω/cm²) measured at the time indicated for each group, compared to control and depicted as % of control. The mean baseline TER at the start of the experiment was 1025.5±71.5 Ω/cm². ★ p<0.05; ★★ p<0.01 and ★★★ p<0.001.
