General Information
Term anterior escort cell ID (Ontology) FBbt:00048535 (Fly Anatomy)
Definition Cell belonging to the anterior-most population of escort cells, adjacent to the cap cells (Eliazer et al., 2014). They display shorter and less elaborate extensions than other escort cells (Banisch et al., 2017) and respond to Hedgehog protein secreted from the cap cells to maintain the germline stem cells (Rojas-Rios et al., 2012).[ FlyBase:FBrf0218031 FlyBase:FBrf0224400 FlyBase:FBrf0235678 FlyBase:FBrf0247148 ]
Also Known As "aEC" ; "aIGS" ; "anterior EC" (for all, see Synonyms field below)
Comment Can be distinguished from other escort cell subtypes based on expression of hh and Pdk1 and lack of GstS1 expression (Rust et al., 2020).
