Draper and the JNK signaling pathway are activated in follicle cells during engulfment. Healthy (A) and degenerating (B–D) egg chambers expressing the JNK reporter puc-lacZ, stained with anti-Draper (yellow), anti-βgal (red) and DAPI (cyan). Draper is expressed at low levels in healthy egg chambers (A′) and increases in expression throughout the progression of engulfment (B′–D′). puckered is not expressed in healthy egg chambers (A″), but is activated during engulfment (B″–D″), merged images are shown in panels (A′″–D′″).
