Movie 3.

The migration area for ventral AFBp cells progressively narrows. Representative ventral view movie of AFBp cells expressing CD4::tdGFP driven by 31F09-Gal4 plus Ay-Gal4 in the abdomen. While AFBp cells migrated posteriorly, they progressively concentrated along the ventral midline, with a subset of cells starting dorsal migration toward the pleurite. Anterior is to the left.
