Supplemental Movie 1
Long term timelapses of wing discs cultured in 20E
Three E-cadherin-GFP-expressing wing discs were imaged in 20E-containing media, acquiring Z-stacks in a 2x2 tiling every 5 min. Shown are 2D projections of the pseudostratified wing pouch layer after tile stitching. Images were rotated and resized for presentation. Dorsal is up, anterior to the left. Frame rate is 10 frames per second.
