Pillar cell loss in cyclodextrin-treated cochleae. (A) Actin staining showing pillar cells in the basal region of a cyclodextrin-treated cochlea. The asterisks mark the areas of missing outer pillar cells, and the cycles mark the areas of missing inner pillar cells. (B) Pearson correlation coefficient analysis reveals a strong and positive correlation in the percentage of loss between inner and outer pillar cells. (C) Comparison of the percentage of loss between inner and outer pillar cells. The level of outer pillar cells is slightly, but significantly, higher than that of inner pillar cells. *** indicates p < 0.001. IPC represents inner pillar cells, and OPC represents outer pillar cells.
