General Information
Term astrocyte-like glial cell ID (Ontology) FBbt:00100505 (Fly Anatomy)
Definition Neuropil associated glial cell of the central nervous system that has a dendritic morphology and elaborates inside the associated synaptic neuropil (Awasaki et al., 2008). Their nuclei are found at synaptic neuropil surfaces and they extend branched filiform or lamelliform processes that pervade the neuropil (Hartenstein, 2011). It expresses prospero, which specifies astrocyte-like, rather than ensheathing, fate in lineages that produce neuropil glia (Peco et al., 2016; Kato et al., 2020).[ FlyBase:FBrf0206543 FlyBase:FBrf0207750 FlyBase:FBrf0214261 FlyBase:FBrf0225669 FlyBase:FBrf0231858 FlyBase:FBrf0245107 ]
Also Known As "ALG" ; "astrocyte" ; "astrocyte-like neuropil associated glial cell" (for all, see Synonyms field below)
