neuroblast NB5-4 |
ID (Ontology) |
FBbt:00001416 (Fly Anatomy) |
| Definition |
Neuroblast that most frequently delaminates at S4 (Schmid et al., 1997). In the embryo, one of these cells can be found in each hemisegment from S3-A10 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in all thoracic segments (Lacin and Truman, 2016) and in the male abdominal 9 neuromere (Birkholz et al., 2013). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 22 (Lacin and Truman, 2016).[ FlyBase:FBrf0098344 FlyBase:FBrf0112030 FlyBase:FBrf0180161 FlyBase:FBrf0221210 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ] |
| Also Known As |
"lineage 22 neuroblast" ; "lineage NB5-4 neuroblast" ; "NB 22" (for all, see Synonyms field below) |
| Comment |
Using DiI with antibody labelling, Schmidt et al. (1997) propose NB5-4 produces 5-9 thoracic neurons or 3-4 abdominal motorneurons with ipsilateral targets. Schmid et al. (1999), also use DiI with en-GFP, but find 2-3 large cells that match descriptions of CCAP/CAP+ neurosecretory cells, along with abdomen-specific interneurons. Also, Schmid et al. (1999) state that NB5-4 delaminates during S5, whilst Schmidt et al. (1997) find that delamination occurs over the period of S3/4 to S5, most frequently at S4, and as such we have chosen to define NB5-4 as a stage 4 neuroblast. |
