Movie 2

Dynamics col1a2⁺ MPCs in quiescent state. col1a2:Gal4; UAS:NTR-mCherry; UAS:Kaede embryos were imaged at 2 dpf for 7.9 hours. col1a2⁺ MPCs cover the surface of the somite. When a col1a2⁺ MPC divides, daughter cells reclaim the same surface area soon after the division. Five different cell divisions are indicated by arrows. Representative snapshots are shown in Figure 2D. Scale bars: 50 μm.
