3D animation of the Atoh1+/− doublet sister cells in their environment. Shown in Fig. 4 (C–C′′). (green) β-catenin; (red) Atoh1; (magenta) EdU; (blue) DAPI. One of the daughter cells of the EdU doublet at the bottom left (position 4–5) is clearly identifiable as Atoh1+, and the other is identified as Atoh1−.
