General Information
Term germarium cap cell ID (Ontology) FBbt:00004868 (Fly Anatomy)
Definition Somatic cell found posterior to the terminal filament. There is a group of 2-6 cells which are usually positioned asymmetrically on one side of the germarium tip, capping the underlying germ line stem cells.[ FlyBase:FBrf0087119 FlyBase:FBrf0235707 ]
Comment They express en and strong LamC; unlike terminal filament cells they also have tj expression (Panchal et al., 2017).
