part of develops from larval ventral nerve cord ventral lateral subperineurial glial cell Surface-associated, subperineurial glial cell located on the lateral surface of the embryonic/larval ventral nerve cord, and is located ventral to the dorsal lateral subperineurial glial cell. It lies at about 30% along the ventro-dorsal axis, and occasionally there are two of these cells per neuromere. It develops from the NB5-6 neuroblast (Beckervordersandforth et al., 2008). VL-SPG belt glial cell fly_anatomy.ontology FBbt:00001288 VFB:FBbt_00001288 At stage 14 the lateral subperineurial glial cells have a vertically elongated 'belt-like' morphology. This suggests that these cells may be the 'belt glia' described by Doe et al., 1991. neuroblast NB5-6 embryonic/larval CNS subperineurial glial cell ectodermal derivative
