Figure 4.

The results (Mean ± SD) of experiments performed in reversed sodium gradient (apical side, KHS1; basolateral side, KHS2) in control conditions and after supplementation of the solution with ion channel blockers. The graph represents: sodium, chloride, potassium transport across epithelial cell monolayer expressed as the concentration change measured 10 min after appropriate solution flow stop; final pH value and the transepithelial potential difference change (N = 7–12 for Cl⁻, Na⁺ and V_te, N = 6 for K⁺ and pH, dependent sample t-test, * p <0.05, ** p <0.01, *** p <0.001). Note different scales for apical and basolateral graphs.
