Fraction values are given as means ± SD. Abbreviations: CD, collecting duct; IM-1, inner medulla-1; Negative fraction, no labeling present at the basal plasma membrane domain; Inconclusive fraction, not possible to either confirm or deny labeling at the basal plasma membrane domain; Positive fraction, definite labeling of E-cadherin at the basal plasma membrane domain.

^aNo statistical test was performed, as control group only included two animals.
