Figure Lengend Snippet: Antibodies for K V 7.4 (A, green) and calretinin (B, cyan) were used as counterstains for calyx membrane (Kv7.4), type II HC cytoplasm (calretinin) and cytoplasm of striolar calyx-only afferents (calretinin). ( A ) Left , Cartoon showing K V 7.4 on the calyx inner face membrane (CIF) and K V 1.8 on the type I HC membrane. SC, supporting cell nuclei. A.1–3 , Adult mouse utricle sections. K V 7.4 antibody labeled calyces on two K V 1.8-positive type I HCs ( A.1 ), four K V 1.8-positive type I HCs ( A.2 ), and two K V 1.8-negative type I HCs from a Kcna10 –/– mouse ( A.3 ). ( B ) Left , Cartoon showing cytoplasmic calretinin stain in calyx-only striolar afferents and most type II HCs, and K V 1.8 on membranes of both HC types. In wildtype utricles, K V 1.8 immunolocalized to basolateral membranes of type I and II HCs (extrastriola, B.1 ). K V 1.8 immunolocalized to type I HCs (striola, B.2 ). Staining of supporting cell (SC) membranes by Kv1.8 antibody was non-specific, as it was present in Kcna10 –/– tissue (striola, B.3 and B.4 ). All scale bars 5 µm.
