Fig. 2. Comparison of Kcne1 expression levels in marginal cells (MCs) and vestibular dark cells in WT mice, untreated Kcne1^−/− mice, and low- and high-dose-treated Kcne1^−/− mice at P30 (n = 4 in each group).

a Kcne1 expression in MCs and vestibular dark cells in WT mice. b Absence of Kcne1 expression levels in MCs and vestibular dark cells in untreated Kcne1^−/− mice. c Kcne1 expression levels were found in some MCs and vestibular dark cells in low-dose-treated Kcne1^−/− mice. d Extensive Kcne1 expression levels in MCs and vestibular dark cells in high-dose-treated Kcne1^−/− mice. Scale bar is 50 µm and applies to all panels. Details of data quantifications are given in the text. Red: phalloidin; Green: KCNE1.
