dorsal channel glial cell [FBbt_00001292]

Surface-associated, channel glial cell that lies at the dorsal-end of the channel above the neuropil. The cells send processes ventrally along the channel, while receiving processes from the A-SPG cells. There are two dorsal channel glial cells per hemisegment and their processes form, along with processes from the ventral channel glia, a sheath structure that covers the inner surface of the dorsoventral channel. It develops from neuroblast NB7-4 (Beckervordersandforth et al., 2008. (Hartenstein, 2011, Beckervordersandforth et al., 2008, Ito et al., 1995)
