stage 3 neuroblast neuroblast NB6-4 Neuroblast that generates only glia in abdominal segments and the maxillary segment and both neurons and glia in thoracic segments and the labial segment (Schmid et al., 1999; Becker et al., 2016). In the embryo, one of these cells can be found in each hemisegment from S2-A8 and A10 (Birkholz et al., 2013; Urbach et al., 2016; Becker et al., 2016). It does not produce a secondary lineage and, at least in thoracic segments, dies in late embryogenesis (Lacin and Truman, 2016). FBbt:00001399 Birkholz et al.
