General Information

| Term |
neuroblast MNB |
ID (Ontology) |
FBbt:00001419 (Fly Anatomy) |
| Definition |
Unpaired neuroblast that forms from the mesectodermal cells of the ventral midline during the fourth wave of delamination (Schmid et al., 1999). During embryonic development, it gives rise to a cluster of around 8 cells with bilateral projections (Schmid et al., 1999). In the embryo, one of these cells can be found in each segment from S1-A10 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in segments S3 to A1 (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 0 (Lacin and Truman, 2016).[ FlyBase:FBrf0072659 FlyBase:FBrf0112030 FlyBase:FBrf0221210 FlyBase:FBrf0228122 FlyBase:FBrf0231327 FlyBase:FBrf0232096 ] |
| Also Known As |
"lineage 0 neuroblast" ; "lineage MNB neuroblast" ; "medial neuroblast" (for all, see Synonyms field below) |
| Comment |
Lacin and Truman (2016) do not show data for segments anterior to S3. |
