neuroblast NB2-3 [FBbt_00001421]

Neuroblast NB2-3 delaminates at S5. It generates three large, round axonless cells at the dorsal side of the thoracic clones which are proposed by Schmid et al., (1999) to be latent leg motorneurons that will extend axons during leg disk eversion. It also generates 2-4 small interneurons at the ventral side of the clone. In the abdominal segments only a single large neuroblast is observed at embryonic stage 17, which either does not divide or all progeny die. This neuroblast resumes proliferation in the larva and generates postembryonic lineage 15 (Lacin and Truman, 2016). Originally referred to as NB1-2 by Doe (1992), this was renamed to NB2-3 by Broadus et al. (1995) to keep the names of row 2 neuroblasts consistent with their position in Schistocerca. Birkholz et al. (2015) suggest that NB2-3 does not generate a postembryonic lineage and NB3-2 generates postembryonic lineage 15, but Lacin and Truman (2016) provide lineage tracing and marker data showing that NB2-3 generates lineage 15.
