Fruit Fly Border Cells (2 of 2) (video) University of Helsinki Share Print E-Mail Loading video... Caption Fruit fly border cells form clusters of six to eight cells, which display directional migration during oogenesis. Migration of border cells in egg chambers can be examined in detail by live-cell microscopy. The egg chamber is in red and border cells (their actin cytoskeletons) are in green. The border cells display protrusions that are important for their migration in the tissue environment. The movie represents an approximately a 2-hour time window of a fruit fly egg chamber.
