embryonic longitudinal glial cell embryonic dorsal longitudinal glial cell VFB:FBbt_00001312 fly_anatomy.ontology Embryonic interface glial cell that has its final (larval) position at the dorsal surface of the neuropil (Ito et al., 1995). There are usually four of these cells per hemineuromere in the late larva (Ito et al., 1995; Beckervordersandforth et al., 2008; Peco et al., 2016). Two of these are a sibling pair that will become larval astrocytes, the other two are siblings to the two ventral longitudinal glia, with one of these pairs becoming astrocytes and the other becoming ensheathing glia (Peco et al., 2016).
