stage 3 neuroblast neuroblast NB1-3 VFB:FBbt_00001404 lineage NB1-3 neuroblast peripheral glioblast Unclear whether this exists in MX or LB, absent from MN (Urbach et al., 2016). fly_anatomy.ontology Neuroblast located at the segment border close to the tracheal pit (Schmidt et al., 1997). It produces glia as well as neurons (Schmidt et al., 1997, 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 secondary lineage (Lacin and Truman, 2016). neuroblast NB1-3 FBbt:00001404 neuroglioblast segmentally-repeated neuroblast
