General Information
Term follicle cell ID (Ontology) FBbt:00004904 (Fly Anatomy)
Definition One of the somatic epithelial cells that is either associated with the germline cyst to form an egg chamber or connecting the egg chambers (Jevitt et al., 2020). Some of these cells, particularly main body follicle cells, can form ring canals to connect to one another (Airoldi et al., 2011).[ FlyBase:FBrf0217092 FlyBase:FBrf0245616 ]
