General Information

| Term |
neuroblast NB1-2 |
ID (Ontology) |
FBbt:00001384 (Fly Anatomy) |
| Definition |
Neuroblast that delaminates in the S2 wave and generates 4-6 intersegmental interneurons. It also produces approximately 20 local interneurons and, in thoracic segments, the semaphorin II (FBgn0011260) positive DC motorneuron. In the embryo, one of these cells can be found in each hemisegment from S2-A9 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in all thoracic segments and the first abdominal segment, generating secondary lineage 1 (Lacin and Truman, 2016).[ FlyBase:FBrf0055900 FlyBase:FBrf0084809 FlyBase:FBrf0112030 FlyBase:FBrf0180161 FlyBase:FBrf0221210 FlyBase:FBrf0228122 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ] |
| Also Known As |
"lineage 1 neuroblast" ; "lineage NB1-2 neuroblast" ; "NB 1" (for all, see Synonyms field below) |
| Comment |
Originally referred to as NB1-1 by Doe (1992), this was renamed to NB1-2 by Broadus et al. (1995) to reflect the fact that it is the only engrailed-expressing anterior row neuroblast in both Drosophila and Schistocerca. |
