General Information

Term

neuroblast NB6-4

ID (Ontology)

FBbt:00001399 (Fly Anatomy)

Definition

Neuroblast that generates only glia in abdominal segments and the maxillary segment and both neurons and glia in thoracic segments and the labial segment (Schmid et al., 1999; Becker et al., 2016). In the embryo, one of these cells can be found in each hemisegment from S2-A8 and A10 (Birkholz et al., 2013; Urbach et al., 2016; Becker et al., 2016). It does not produce a secondary lineage and, at least in thoracic segments, dies in late embryogenesis (Lacin and Truman, 2016).[ FlyBase:FBrf0112030 FlyBase:FBrf0221210 FlyBase:FBrf0228122 FlyBase:FBrf0231327 FlyBase:FBrf0231386 FlyBase:FBrf0232096 ]

Also Known As

"lineage NB6-4 neuroblast" ; "neuroblast NB6-4"

Comment

Birkholz et al. (2015) claim this NB generates postembryonic lineage 11.
