The caspase enzymes

The cells labeled with fluorescent dyes in the primary tissues of the wing (left), eye (center) or leg (right) in the fruit fly larva, do not migrate when they have normal caspase activity (top row). When the caspases are removed, these cells begin to migrate after irradiation to other parts of the tissue (bottom row)
