At postnatal day (P) 5 the sensory epithelia are patterned into three rows of outer hair cells (OHCs) and one row of inner hair cells (IHCs) with no obvious structural abnormalities. The bundles of OHCs appear similar in size to those of wild-type mice and form a normal staircase pattern. The hair bundles of OHCs have a slightly more rounded morphology, especially in basal regions of the cochlea. The morphology of IHCs is not significantly altered. Hair cells are maintained in the presence of gentamicin, an aminoglycoside antibiotic that enters hair cells through their transduction channels and normally causes hair cell death. Mechanotransduction currents are very small in P4 hair cells and completely absent in P7 hair cells. Membrane potential, outward-evoked currents and nonlinear capacitance are normal in OHCs. No difference in the expression or localization of tip link proteins CDH23 and PCDH15 or ATP2B2, MYO7A, ESPN and WHRN proteins at P5-P8 in hair bundles of hair cells. No difference in the number of tip links in IHCs and OHCs at P7-P8. No difference in the levels of catecholamines, including norepinephrine, homovanillic acid (HVA) and norepinephrine, or serotonin levels in the inner ear. Loss of reverse polarity currents."
