Colcemid treatment disrupts microtubule meshwork integrity and affects the pulsatility of the amnioserosa cells. The apical microtubule cytoskeleton (visualized using Jupiter GFP) and constriction pulses of amniserosa cells (visualized using Ecad GFP) upon colcemid treatment. The panels in B are zoomed in views of the images in A. Scale bar -20 μm (A) and 10 μm (B). (Related to Figs 8, S7)
