Live imaging of membrane digitations at Par3 patches in early stage FP cells. wt embryo mosaically expressing Centrin-GFP, Membrane-GFP (green) and Par3-RFP (magenta). White arrows point at the BB at the beginning and at the end of the movie. Yellow arrows at t=0 and t=68 min point at membrane digitations originating from the posterior and the anterior Par3 patches, respectively. Images were taken every 4 min during the 7 s to 8 s stages time-frame. Dorsal view. Corresponds to Fig4F.
