Exosomes from heat shock preconditioned BMSCs ameliorated cisplatin-induced hair cell loss in the middle turns of the cochlea. Representative Myosin 7a staining in different groups (A) and quantification of hair cells (B). The data were shown with mean ± SD. Eight fields of each mice and six mice in each group were counted. ***p < 0.001 compared to control, #p < 0.05, ##p < 0.01 compared to Cisplatin, ^^p < 0.01 compared to Cisplatin + Exo. One-way ANOVA followed Tukey’s multiple comparisons test
