General Information
Term stalk follicle cell ID (Ontology) FBbt:00004910 (Fly Anatomy)
Definition Cell that is part of the stalk connecting adjacent egg chambers in a vitellarium. Each stalk is usually composed of 5-8 interdigitating stalk follicle cells.[ FlyBase:FBrf0007735 FlyBase:FBrf0090554 FlyBase:FBrf0247148 ]
Also Known As "interfollicle cell" ; "interfollicular stalk cell" ; "stalk cell"
Comment Can be identified by expression of CG46339 (Rust et al., 2020).
