General Information
Term main body follicle cell ID (Ontology) FBbt:00005402 (Fly Anatomy)
Definition Follicle cell that overlies the oocyte (Wu et al., 2008). Along with the posterior terminal follicle cells they form a columnar epithelium from stage 10, which deposits eggshell components (Wu et al., 2008). These cells are connected to one another by ring canals (Airoldi et al., 2011).[ FlyBase:FBrf0205319 FlyBase:FBrf0217092 ]
Also Known As "central main body follicle cell" ; "MBFC" ; "oocyte associated follicle cell"
