Oogenesis Cinemas:
The following are several movies of dorsal follicle cell migrations. These migrations, coupled with secretion of eggshell proteins, are responsible for the formation of the dorsal respiratory appendages. The movies are in a Quicktime format.


cy2xGFPmoe: Follow a developing egg chamber through the process of dorsal follicle cell migration. This is a lateral (side) view, so you can see only one of the two populations of migrating follicle cells. Timelapse confocal microscopy was used to capture these follicle cells in motion. The cells can be visualized because they are expressing the GFP-moesin fusion protein. 13.8MB

TL1Z23.qt: Lateral view of a developing egg chamber, followed by a Z-series (a series of images taken at changing depth increments) to focus on a different optical section of the egg chamber. Finally, the continuing development of the same egg chamber is shown in a different plane. 28.3MB

dorsallatjd.qt: Dorsal lateral view of migrating follicle cells. This movie shows 3 Z-series at 3 different time points during the migration. 15MB

TL1S12A.qt: Close-up of the migrating dorsal follicle cells. Note the dramatic movements of the cells at the tip of the forming appendage. 5.8MB

TLZ2aa-0.14.qt: Z-Series of a an egg chamber at an early point during dorsal follicle cell migration (stage 10). 2MB

TLZ2aa-aq01a.qt: Time lapse movie of the development the same egg chamber from the Z-series above (only one plane is shown). Notice the dynamic activity at the leading edge of the migrating follicle cells. 2.7MB
