Long term survival of hair cell-like cells. 8 weeks after transgene delivery, there were still numerous Myosin VIIa-positive/tdTomato-positive HCLCs in both treatment groups (a). Scatter plots showing counts of Myosin VIIa-positive and tdTomato-positive cells (b) demonstrate patterns similar to those seen at 4 weeks; namely, similar proportions tdTomato-positive cells that are Myosin VIIa-positive in the apex and base of each group, and a higher proportion of Myosin VIIa-positive/tdTomato-positive cells in the Ad.Gfi1.Atoh1 group than in the Ad.Atoh1 group. The total number of new Myosin VIIa-positive cells was significantly higher in the Ad.Gfi1.Atoh1 group than in the Atoh1-only group (c); although difference were not significant due to small sample size at the 8-week time point. Scale bar = 100 μm.
