Time-lapse movie of BC migration (10 frames/s) starting from specification of the cluster and the ability of the cluster to acquire forward protrusion, followed by cell-on-cell migration to the anterior border of the oocyte. GFP expression is driven by slbo-Gal4 to label the BC cluster in green. Nuclei are labeled with Ub-His2A-RFP in magenta. Egg chamber genotype: w1118/+; slbo-Gal4, UAS-GFP, Ub-His2A-RFP/+.
