Fig. 3. Epithelium height measured in isosmotic conditions (Ctrl), and after 5 min and 45 min exposure to hypotonic stress (decrease of Ringer osmolarity from 315 mOsm to 175 mOsm). Values are means ± S.E.M. Statistical analysis was performed by one-way ANOVA repeated measures test and Newman-Keuls multiple comparison test. ^**P<0.01.
