The Drosophila ovary. (A) An image of a single ovariole stained with DAPI to label DNA. Oogenesis begins in the germarium and ends with a fully developed Stage 14 egg chamber. During the late stages of oogenesis, nurse cells (NCs) dump their cytoplasm into the oocyte and are eliminated. This dramatic change is readily seen when comparing the Stage 10 egg chamber in which NCs take up about half of the egg chamber (inset, pink region) to Stage 14 when NCs have been eliminated (inset, yellow region). (B) Stretch follicle cell (SFC) > Myr-GFP Stage 11 egg chamber stained with DAPI. SFC membranes (green, arrow) begin to surround NCs as they dump their cytoplasmic contents into the oocyte. (C) SFC > Myr-GFP Stage 13 egg chamber stained with DAPI. SFC membranes (green, arrow) completely surround NCs. All scale bars = 50 µm.
