OB and RMS astroglia exhibit a vast morphological diversity. (A) Pial clones exhibiting a sheet-like morphology. (B) ONL astroglia projecting thick processes into the GL. (C) Clones with their somata distributed over the interglomerular walls. (D) Clones with their somata gaining access to the glomerular neuropil. (E,F). Protoplasmic astrocytes distributed in small groups. (G) Protoplasmic astrocytes oriented along the layer boundaries. (H) Radial-like cells. (I) Twin astrocytes. (J) Individual protoplasmic astrocytes surrounding the limits of the SEZ/RMS. (K) Poorly elaborated cells in small groups. (L,M) Radial-like cells sending their projections into the SEZ/RMS core and forming gliotunnels. This diagram was elaborated from the cell outlines.
