General Information
Term longitudinal glioblast ID (Ontology) FBbt:00001405 (Fly Anatomy)
Definition 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).[ FlyBase:FBrf0054242 FlyBase:FBrf0055900 FlyBase:FBrf0205499 FlyBase:FBrf0221210 FlyBase:FBrf0231327 FlyBase:FBrf0231858 FlyBase:FBrf0232096 ]
