neuroblast NB3-2

ID: FBbt_00001388

Neuroblast that delaminates at S1 and generates around 6 motorneurons and a cluster of local interneurons (Schmid et al., 1999). 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 T1 to A1 segments (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 7 (Lacin and Truman, 2016).

Birkholz et al. (2015) suggest that NB3-2 generates postembryonic lineage 15 and NB4-2 generates postembryonic lineage 7, but Lacin and Truman (2016) provide lineage tracing and marker data showing that NB3-2 generates lineage 7. Lacin and Truman (2016) do not show data for neuromeres anterior to S3 (labial).
