Cell populations associated to EP granular structures. A Representative sections of zone 2 from a 3-month-old SAMP8 mouse immunostained with anti-GFAP (green), anti-vimentin (red), and IgM (white) antibodies, showing merged and separated channels; B Representative sections of zone 2 from a 3-month-old SAMP8 mouse immunostained with anti-cytokeratin (green), anti-vimentin (red) and IgM (white) antibodies, showing merged and separated channels (B). All sections were stained with Hoechst (cell nuclei, blue). White arrows indicate EP granules in the pia mater; orange arrows indicate EP granules in the root of the choroid plexus. Scale bars: 100 µm
