General Information
Term polar follicle cell ID (Ontology) FBbt:00004907 (Fly Anatomy)
Definition Follicle cell at the anterior or posterior pole of the egg chamber. Initially they are found in clusters of 3-8 per pole, then excess cells undergo apoptosis during stages 2-5, leaving 2 per cluster.[ FlyBase:FBrf0205319 FlyBase:FBrf0247148 ]
Also Known As "polar cell"
Comment Can be identified by expression of upd1 (Rust et al., 2020).
