Localization of proteins in rda/rda vestibular hair cells. Reslice projections of confocal z-stacks of phalloidin- and antibody labeled vestibular hair cells from +/rda (left) or rda/rda (right) mice. A, B, MYO6 in P12 utricle hair cells; maximum projection of 5 μm depth. MYO6 is present in the apical protrusions of rda/rda hair cells. C, D, PTPRQ in P12 utricle hair cells; maximum projection of 5 μm depth. PTPRQ is also present in the apical protrusions of rda/rda hair cells, and in an expanded zone in hair bundles. E, F, RDX in P8 utricle hair cells; average projection of 8 μm depth. ARF6 is more apically located in rda/rda hair cells. G, H, ARF6 and EEA1 in P7 utricle hair cells; average projection of 0.8 μm depth. ARF6 is more apically located in rda/rda hair cells. I, J, CLTC in P7 utricle hair cells; average projection of 8 μm depth. Increased number of high-expressing cells in rda/rda utricles. Panel full widths: 40 μm.
