(2015) suggest that NB3-4 generates postembryonic lineage 18, but Lacin and Truman (2016) identify lineage 25 and provide lineage tracing data showing that it is generated by NB3-4. Lacin and Truman (2016) only find this cell in thoracic segments in the embryo. NB 25 Neuroblast that delaminates at S5 and produces a motorneuron, located on the posterior boundary of the clone, that projects into the anterior root of the ISN, as well as several interneurons (Schmid et al., 1999). In the embryo, one of these cells can be found in each hemisegment from S1-A10 (Birkholz et al., 2013; Urbach et al., 2016). In the larva, it resumes proliferation in all thoracic segments, producing postembryonic lineage 25, which contains motor neurons and glia (Lacin and Truman, 2016). stage 5 neuroblast neuroglioblast segmentally-repeated neuroblast
