General Information
Term thoracic neuroblast NB6-4 ID (Ontology) FBbt:00001400 (Fly Anatomy)
Definition Neuroblast NB6-4 found in a thoracic segment. Its first division produces a daughter cell that generates only glia and a daughter cell that produces ganglion mother cells that give rise to neurons (Akiyama-Oda et al., 1999). It dies in late embryogenesis (Lacin and Truman, 2016).[ FlyBase:FBrf0108424 FlyBase:FBrf0112030 FlyBase:FBrf0231327 ]
Also Known As "NB6-4T" ; "neuroblast NB6-4 of thoracic segment" ; "neuroblast NB6-4 of thorax" (for all, see Synonyms field below)
