Movie 1

Time lapse of a subset of a pupal leg disc expressing alphaCat-TagRFP in the ap domain (which encompasses the t4-t5 fold) and the GC3Ai construct to reveal caspase activity and thus visualise apoptotic cell. The apoptotic cell shape can be followed on the apical (top) and sagittal (bottom) sections. Note the reduction of the apical surface of the apoptotic cell on the apical views, the transient deformation of the apical surface on the sagittal views and the formation of apoptotic bodies.
