General Information
Term larval A-subperineurial glial cell ID (Ontology) FBbt:00001259 (Fly Anatomy)
Definition A large subperineural glial cell of the embryo or larva that lies anterior to the anterior segment border and anterior commissure and medial to the longitudinal connective in each abdominal and thoracic neuromere, (Klambt and Goodman, 1991; Ito et al., 1995). It sends a process to the dorsoventral channel (Ito et al., 1995). These cells have different neuroblasts of origin in different neuromeres (Beckervordersandforth et al., 2008).[ FlyBase:FBrf0054242 FlyBase:FBrf0057603 FlyBase:FBrf0082171 FlyBase:FBrf0205499 ]
Also Known As"A subperineurial glial cell" ; "A-SPG"
