Figure 3.

Inflammatory macrophages engulf debris at a wound. (Left panel) Low-magnification image of the ventral surface of a stage 15 embryo. An epithelial wound (asterisk) has been generated by laser ablation resulting in macrophage recruitment (LifeAct-GFP driven by sn-GAL4, green). (Middle panel) Magnified image of region outlined by the dashed box. Macrophages encircle the wound edge (dashed circle) and phagocytose debris (arrow). (Right panel) Same image with inclusion of whole embryo tissue label (sqh-mCherry-Moesin, red). Internalized labeled tissue is present in macrophages (barbed arrows) originating from wound and earlier apoptotic events.
