Their identity is established by the expression of the gene glial cells missing (gcm), which results in expression of reversed polarity (repo), often used as a marker for lateral glia (Jacobs, 2000). This includes perineurial and subperineurial glia of the central and peripheral nervous systems, cell body (cortex) glia, wrapping glia and some of the neuropil associated glia (Beckervordersandforth et al., 2008). There are around 25 of these per abdominal hemisegment in a stage 16 embryo (Beckervordersandforth et al., 2008). VFB:FBbt_00047861 FBbt:00047861
