That the sub-perineurial glial cells do not derive from the mesoderm is suggested by Edwards et al., (1994), in which they show the presence of these cells in delta (FBgn0000463) mutant embryos.

Inner cell layer of the perineurium. Probably not derived from the mesoderm (Edwards et al., 1994), these cells form an ion permeability barrier analogous to the blood-brain barrier of vertebrates (Hartenstein and Jan, 1992).
