Subcellular distribution of BK and KCNQ4 channels in OHCs. (A) 3D reconstruction of confocal image stacks of an OHC (whole-mount preparation, midbasal turn) stained for KCNQ4 (red) and synaptophysin (green). (B)3D reconstruction of confocal image stacks of an OHC-efferent synapse (midbasal turn) stained for BK (red) and synaptopysin (green). Note that BK is localized at the postsynaptic side of the synaptopysin-immunopositive efferent presynapse. (Bar in A = 10 μm; in B = 2.5 μm.)
