Figure 5.

The HCs regenerated by DBZ treatment had more mature stereocilia bundles compared to those regenerated by DAPT treatment. (A‐A1) In the neomycin‐treated group, some of the HCs were absent and the bundles of the surviving HCs were arranged in abnormal structures. (B‐B1) In the 5 μM DAPT‐treated group, the newly regenerated HCs had short and disordered immature bundle structures in the apical turn of the cochlea. (C‐C1) In the 10 μM DBZ‐treated group, the newly regenerated HCs had longer and more organized mature bundle structures than the DAPT‐treated group
