neuroblast NB7-2

ID: FBbt_00001392

Neuroblast that delaminates at S2 in the intermediate column and generates around 12 primary interneurons (Schmid et al., 1999). In the embryo, one of these cells can be found in each hemisegment from S1-A9 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in segments S3-T3, but its secondary lineage is dramatically reduced in T3 (Lacin and Truman, 2016). The neurons that develop from this neuroblast after larval hatching form postembryonic lineage 11 (Lacin and Truman, 2016).

Birkholz et al. (2015) suggest that NB7-2 does not generate a postembryonic lineage and NB6-4 generates postembryonic lineage 11, but Lacin and Truman (2016) provide lineage tracing and marker data showing that NB7-2 generates lineage 11. Lacin and Truman (2016) do not show data for neuromeres anterior to S3 (labial).
