Movie 6.

Live imaging of BB movements in a FP cell displaying a membrane digitation between BB and the anterior membrane (yellow arrow at t=18 min). wt embryos were injected with Centrin-GFP (green) and membrane-Cherry (magenta) mRNAs at the one-cell stage. Membrane digitations between the posterior membrane and BB can also be seen at t=10min, t=26min and t=66min. White arrows point at the 9 BB. Images were taken every 2 minutes during the 8 s to 10 s stages time-frame. Dorsal view. Corresponds to Fig3A lower row.
