Movie 1.

AFBp cells were distributed in a quasi-two-dimension manner in the abdomen. Representative 3D rotated image of AFBp cells expressing CD4::tdGFP (cell membrane, green) and RedStinger (nucleus, magenta) driven by 31F09-Gal4 plus Ay-Gal4 at the pleurite (47 h APF). Numbers in the movie refer to the scale in micrometers. The z-axis indicates depth in z-series image sequences, with smaller numbers to the body cavity. Anterior is to the left, and dorsal is up in the first frame of the movie.
