Annotated milestones observed during centripetal migration. A series of eight time-lapse Movies that include the data from Fig. 2A-G showing different egg chambers undergoing each of the milestones identified. Crosssectional views are shown, labeled with a membrane localized fluorophore (TJ-Gal4 ≫ UAS-Myr::tdTomato). Anterior is oriented to the left, and dorsal is up. Each milestone is briefly listed along with a short description. Colored arrows indicate features that define each milestone. A five-hour time-lapse of a single stage 10B egg chamber progressing through all milestones is displayed at the end of the Movie. Full genotypes for this Movie are available in Table S2.
