Distribution and expression patterns of cadherins and catenins in the mouse OE. (A) Immunostainings for E-cadherin, N-cadherin, β-catenin, αE-catenin, and αN-catenin in the OE on P28. (B) Immunostainings for E-cadherin, N-cadherin, β-catenin, αE-catenin, and αN-catenin in sections of the mouse OE on P28. Arrowheads indicate Bowman’s glands. (C) In situ hybridizations in sections of the OE on P28. Each panel shows the staining for DAPI (blue), OMP (green), and mRNA for each cadherin (red). Dotted lines show the basal lamina. The two-way arrows indicate SC or OC layers.
