It develops from neuroblast 1-3 (von Hilchen et al., 2008) and gives rise to a subperineurial glial cell (von Hilchen et al., 2013). VFB:FBbt_00110110 fly_anatomy.ontology The position of the cell body of ePG7 is variable: it is found at its position 70% of the time. It can also be found at the positions of ePG6 (8%), ePG8 (21%) or ePG9 (1%). This analysis was done using specific cell markers and taking into account which nerve the cell is associated with (von Hilchen et al., 2008).
