Cisplatin dose-dependently kills wild-type murine hair cells. (A) Cochlear explants were dissected from P3 wild-type C57/BL6J mice and cultured overnight in DMEM/F12 culture medium. Then, the cochlear explants were exposed to cisplatin at different concentrations for 2 days. The samples were fixed and labeled with an antibody against β2-spectrin, a hair cell marker. Note, OHCs (arrowheads) were more susceptible to cisplatin than IHCs (arrows). Scale bar: 10 μm. (B) Numbers of hair cells per 100 μm (3 mice per group). Data are represented as the mean ± standard error (SE). Two-way ANOVA followed by Bonferroni post hoc test was performed (**p < 0.01 and ***p < 0.001).
