ARSs are distributed along the SPG intercellular borders. (A–I) Nerve cords were dissected from third instar larvae, labeled with moesin-GFP (A–C), Lifeact-GFP (D–F), or CD8-GFP (G–I), driven to be expressed in the SPG cells, and then double labeled with phalloidin (Phall). The GFP labeling is shown in A, D, and G, phalloidin in B, E, and H, and their merged images in C, F, and I. The insets in each panel represent high magnification of the region marked by an arrow in the nerve cords. Note that the ARSs are distributed along the borders of the large SPG cells. Overlap between GFP and phalloidin is observed.
