Ovariole of female fruit fly

Caption

The larger spheres (two can be seen) are egg chambers. Each chamber contains a future egg and associated nurse cells (some of these can be seen as hazy out of focus outlines). The covering sheet is made of follicle cells (shown in blue). Fluoxetine (Prozac) increases division (in magenta) of follicle cells in flies.
