Stage 9 egg chamber showing border cells initiating migration and early migration. Time points from 57 min 20 s to 113 min 20 s were used for further analysis. The video shows all confocal sections for the GFP channel (green above; white below) overlaid with the central section for the red channel (FM 4–64, membrane dye). The anterior is shown on the left, and the oocyte is shown on the right. The time stamp is in minutes, and the bar is 20 µm. The genotype is slboGal4, UAS-10×GFP/+ (control).
