Transient Wnt Activity after Hair Cell Ablation, Related to Figure 4
Neuromast O2 before (52hpf) and after hair cell ablation through neomycin treatment. Frames from a time-lapse sequence are shown; the numbers indicate hours after ablation. Arrows indicate Wnt-active mesenchymal cells lying outside of the neuromast; arrowheads show Wnt-reporter expression in neuromast support cells. Newly formed hair cells are marked by asterisks. The single hair cell already present at 2:30 hours after the ablation (indicated by circles) was presumably beginning to differentiate at the time of the ablation. Scale bar represents 20 μm.
