General Information
Term embryonic peripheral glial cell 3 ID (Ontology) FBbt:00110106 (Fly Anatomy)
Definition Embryonic peripheral glial cell associated with the intersegmental nerve (ISN). It is the most lateral cell located in the transition zone between the CNS and the PNS (exit area), laterally to ePG2. It develops from neuroblast 1-3 (von Hilchen et al., 2008) and gives rise to a subperineurial glial cell (von Hilchen et al., 2013).[ FlyBase:FBrf0204826 FlyBase:FBrf0222452 ]
Also Known As "ePG3"
Comment The position of the cell body of ePG3 is variable. It is the most lateral cell of the exit zone 46% of the time, but it can also be found at the positions of ePG1 (8%) or ePG2 (46%). This analysis was done using specific cell markers and taking into account which nerve the cell is associated with (von Hilchen et al., 2008).
