General Information
Term embryonic/larval oenocyte precursor ID (Ontology) FBbt:00007021 (Fly Anatomy)
Definition Embryonic/larval oenocyte precursors first become apparent during stage 11 when a small group of cells encircling each chordotonal organ precursor cell C1 become sickle shaped, making a double ringed 'whorl' around C1. Shortly afterwards (stage 11-12) these cells delaminate in two waves, (inner cells first) and migrate away to form an 'abdominal larval oenocyte group'.[ FlyBase:FBrf0134578 ]
Also Known As "larval oenocyte precursor"
