From: Postembryonic development of transit amplifying neuroblast lineages in the Drosophila brain
DM neuroblast lineages contain both neurons and glial cells. (A, B) Consecutive confocal images (from dorsal to ventral) of a DM MARCM clone (GFP, green). Neuronal cells are Elav-positive and glial cells are Repo-positive (blue, arrowheads). (C) Scheme of the DM lineage: note that localization of the glial cells is distal to the neuroblast in the clone. (D) A close-up view of the DM glial cells. Secondary neuronal cells, their projections and common axonal bundle are stained with anti-Neurotactin (Nrt, red) and glial cells are Repo-positive (blue). Glial cells extend processes along the axonal bundle (asterisk).
