General Information
Term medial-most cell body glial cell ID (Ontology) FBbt:00001299 (Fly Anatomy)
Definition Cell body glial cell that lies close to the midline of the embryonic/larval ventral nerve cord. It lies between 10-20% along the mediolateral axis, and at approximately 50% along the anterioposterior axis, and flanks the ventral unpaired median (VUM) neuron cluster on the midline. In the early larva, each thoracic hemineuromere has two medial-most cell body glial cells, whilst each abdominal hemineuromere has one (Ito et al., 1995). It develops from the NB6-4 neuroblast (Beckervordersandforth et al., 2008).[ FlyBase:FBrf0054242 FlyBase:FBrf0068598 FlyBase:FBrf0082171 FlyBase:FBrf0205499 FlyBase:FBrf0214261 ]
Also Known As"medial-most cortex glial cell" ; "medial-most cortex-associated glial cell" ; "medialmost cell body glial cell" (for all, see Synonyms field below)
CommentThe medial-most cell body glial cells are likely the VUM-support cells described by Klambt and Goodman (1991), and Menne and Klambt (1994) (Ito et al., 1995).
