Mosaic wing disc with wild-type clones expressing UAS-GFP (GFP, cyan). TRE-RFP expression is reporting JNK pathway activity (gray or magenta). Antibody staining against the cleaved effector caspase (Dcp1) visualizes apoptosis (gray or yellow). Phalloidin visualizes cortical F-actin (gray). Please note that JNK activity is physiologically elevated at the A/P compartment boundary in wing discs at this developmental stage. White frame marks region shown to the right in (A'). The dotted line indicates stitching of confocal images with different z positions. Image sets are shown at the same scale.
