General Information
Term stretch follicle cell ID (Ontology) FBbt:00004908 (Fly Anatomy)
Definition Follicle cell of the germarium that migrates posteriorly and covers the nurse cells during stage 9. There are approximately 50 of these follicle cells that flatten to form a squamous domain over the nurse cells.[ FlyBase:FBrf0135734 FlyBase:FBrf0247148 ]
Also Known As "NCFC" ; "nurse cell follicle cell" ; "nurse follicle cell" (for all, see Synonyms field below)
Comment Can be identified based on coexpression of dpp and cv-2 (Rust et al., 2020).
