Co-treatment with DAPT and <t>QS11</t> promotes SC proliferation and HC regeneration in the cochlea in vitro in an age-dependent manner. The P0–P1 cochleae were cultured with 10 μM QS11 a or 5 μM DAPT b or with both QS11 and DAPT c for 3 days. There were significantly greater numbers of EdU + /Sox2 + cells and EdU + /Myo7a + cells in the apex of the cochlea compared to the DAPT-only group and the QS11-only group. The EdU + cells in the DAPT + QS11 co-treated cochleae were seen throughout the sensory cell region in the apical turn. Scale bar = 20 μm. A control cochlea treated with vehicle is shown in d (Scale bar = 50 μm). The histograms show the differences in the numbers of EdU + cells e and Myo7a + cells f between these groups. The cells were counted per 100-μm length along the cochlea. The numbers of EdU + cells were counted between the outer HCs and the inner HCs. (* p < 0.05, ** p < 0.01, *** p < 0.001). The P4 cochleae were cultured with 10 μM QS11 g – g ’” or 5 μM DAPT h – h ’” or with both QS11 and DAPT i – i ’” for 3 days. The number of EdU + and Myo7a + cells was greater than in the DAPT-only and QS11-only groups, while the numbers of Myo7a + cells and EdU + cells in the sensory area were fewer compared to P0–P1 cochleae with the same treatment. Scale bar = 20 μm. The histograms show the differences in the numbers of Myo7a + cells j and EdU + cells k in the apical turn of the cochlea between the P0–P1 mice and the P4 mice for the different treatment groups. The cells were counted per 100-μm length along the cochlea. The numbers of EdU + cells were counted between the outer HCs and the inner HCs. (* p < 0.05, ** p < 0.01, *** p < 0.001)

Co-treatment with DAPT and QS11 promotes SC proliferation and HC regeneration in neomycin-damaged cochleae in vitro. The P0–P1 cochleae were cultured with 1.0 mM neomycin for 16 h, then treated with either media only a – a ”, 5 μM DAPT b – b ”, 10 μM QS11 c – c ”, or both d – d ” for another 7 days. The number of Myo7a + cells was decreased in the apical, middle, and basal turns of the cochlea, especially in the basal turn and middle turns in the control and QS11-only groups. However, the numbers of EdU + /Sox2 + cells and EdU + /Myo7a + cells were increased in the DAPT-only and DAPT + QS11 groups, especially in the apical turn of the cochlea. In addition, there were many more EdU + cells in the sensory area of the cochlea than in the DAPT-only group, especially in the apical turn of the cochlea (scale bar = 20 μm). The histograms show the differences in the numbers of EdU + cells e and Myo7a + cells f in the different turns of the cochlea. The cells were counted per 100-µm length along the cochlea, which was measured between the outer HCs and the inner HCs (** p < 0.01, *** p < 0.001). The P0–P1 Atoh1-eGFP transgenic mouse cochleae were cultured with 2.0 mM neomycin for 16 h then treated with either media only g – g ”, 5 μM DAPT h – h ”, 10 μM QS11 i – i ”, or both j – j ” for another 7 days. Myo7a + cells were clearly lost in the basal turn and the middle turn of the cochlea in the control and QS11-only groups, and there were no EdU + /Sox2 + cells or EdU + /Myo7a + cells in the sensory domain in these two groups. However, there were some EdU + /Sox2 + cells and EdU + /Myo7a + cells in the sensory area of the cochleae in the DAPT-only and the combination groups, with more cells seen in the combination group compared to the DAPT-only group, especially in the apical turn of the cochlea.
