stage 3 neuroblast longitudinal glioblast glial precursor FBbt:00001405 LGB glioblast VFB:FBbt_00001405 fly_anatomy.ontology Glioblast that generates the interface (longitudinal) glia of the embryo, which become neuropil glia in the larva (Beckervordersandforth et al., 2008). It delaminates during embryonic stage 10, in the third wave of delamination (Doe, 1992). In the embryo, one of these cells can be found in each hemisegment from S2-A10 (Birkholz et al., 2013; Urbach et al., 2016). It divides once, symmetrically, to produce two glial cells (Klambt and Goodman, 1991). One of these cells appears to become the lateral posterior longitudinal glial cell and the other proliferates to generate a total of eight embryonic interface glial cells (Peco et al., 2016). It does not generate a secondary lineage (Lacin and Truman, 2016). GP neuroblast GP glioblast segmentally-repeated neuroblast
