Wnk1 and Wnk1/Hsn2 expression in the hippocampus of adult mice.

(A–F) Coronal sections of adult mouse hippocampus were examined using ISH detection with anti-sense Wnk1, anti-sense Wnk1/Hsn2 and sense Wnk1/Hsn2 (negative control) riboprobes, respectively. (B, D, and F) Corresponding sections were stained with cresyl violet. Arrows in A and C indicate increased signal in the CA2 and CA3 hippocampal areas with both probes. Asterisks indicate non-specific labeling in the corpus callosum (*), fimbria (**) and limitans (***).CA1–CA3  =  Cornu Ammonis area 1 to 3; DG  =  dentate gyrus; Ha  =  habenula; CP  =  choroid plexus.
