General Information
Term FBbt:00007137 ID (Ontology) FBbt:00007137 (Fly Anatomy)
Definition A cyst of female germ cells interconnected by ring canals. Each cyst originates from a single cystoblast which divides to form 16 cyst cells. These become enveloped in a follicle cell epithelium as they pass through region 2 of the germarium. Cysts that have left the germarium are termed egg chambers.[ FlyBase:FBrf0064777 ]
