Hair cells of P1mo CBA and C57 mice were intact from base to apex when stained with rhodamine-phalloidin (A). At P3mo, C57 mice showed occasional hair cell loss at the basal turn of the cochlea (B). At P6mo, multiple hair cell loss at the basal and mid turn of the cochlea was observed in C57 mice (C). CBA mice showed occasional hair cell loss at P6mo of age. ^*Representative sites of hair cell loss. Scale bar 10 µm.
