General Information
Term embryonic optic neuroblast ID (Ontology) FBbt:00048429 (Fly Anatomy)
Definition Optic neuroblast that delaminates from the neuroepithelium during the embryonic stage (Hakes et al., 2018). These cells are produced continuously between embryonic stages 12 and 17, with a final number of around 8 or 9 per brain lobe (Hakes et al., 2018). They express similar markers to larval neuroblasts and produce neurons and glia during embryogenesis (Hakes et al., 2018). They enter G0 quiescence prior to larval hatching and persist into the larval stage, they are among the last neuroblasts in the larval brain to reactivate (Hakes et al., 2018).[ FlyBase:FBrf0240123 ]
Also Known As"EON"
