stage 5 neuroblast neuroblast NB5-5 VFB:FBbt_00001425 fly_anatomy.ontology Schmid et al. (1999) suggest that NB5-5 may be equivalent to clone Y described by Schmidt et al. (1997). A neuroblast similar to NB5-5 was found in the embryonic mandibular (S1) neuromere by Urbach et al. (2016), but NB5-5 is absent from S2 and S3 and this S1 cell had several differences in marker expression, making serial homology unclear. neuroblast NB5-5 clone Y Neuroblast that delaminates at S5 and generates 8-11 large neurons including interneurons and neurosecretory cells (Schmid et al., 1999). In the embryo, one of these cells can be found in each hemisegment from T1-A9 (Birkholz et al., 2013; Urbach et al., 2016). It does not generate a postembryonic lineage and, at least in thoracic segments, it is lost before the end of embryogenesis (Lacin and Truman, 2016). lineage NB5-5 neuroblast FBbt:00001425 segmentally-repeated neuroblast
