Figure 1. Expression patterns of gcm and repo genes during glial cell lineage differentiation.

(A) Gcm is expressed in neuroglioblasts, glioblasts, and transiently in immature glia cells [8], [24]. Exceptionally, expression of gcm is observed in a very few number of interneurons in the ventral nerve cord from L1 to adult stage [9]. (B) A scheme of the expression pattern of repo. In addition, Repo is detected in longitudinal glioblasts and glial cells [25]. (C) Existence of different types of glial cell lineage and neuronal cell lineage cells at developmental stages.
