Movie 3.

Probability map of extrusions, SOPs and divisions in a pupal wing. z-projection of a WT pupal wing expressing E-cad::GFP (grey) from (Etournay et al., 2015), overlayed with the probability map of detection of extrusions (yellow) and cell divisions (magenta). E-cad channel is shown separated on the bottom. Distal on the right, proximal on the left. Scale bar=50μm. Note that we only took in consideration the probability overlapping the wing.
