Fig. 3. (Α). Osmotic water permeability (P_f) of benign (MeT-5A) and malignant (M14K, ZL34) mesothelial cells that were exposed to high glucose hyper-osmotic stress for 24 hours. ** p<0.01 as compared to MeT-5A. Comparison of P_f of MeT-5A (Β), Μ14Κ (C) and ZL34 (D) cells without and with inhibition of AQP1 by HgCl₂. ***p<0.001 compared to no treatment.
