Figure 3

Dorsal root ganglion of a Beagle dog (a,d,g), a C57BL/6 mouse (b,e,h), and a gray langur (Semnopithecus sp.) (c,f,i). (ac) Glial fibrillary acidic protein (GFAP), 2′,3′-cyclic-nucleotide 3′-phosphodiesterase (CNPase) (df), and (gi) glutamine synthetase (GS). Most satellite glial cells (SGCs) are immunopositive for GFAP and CNPase in dogs and monkeys, whereas most murine SGCs lack expression of these markers (arrowheads). Note single CNPase+ SGC (arrow, e). In contrast, GS represents a good marker for murine and simian SGCs but not for canine SGCs. There are SGCs positive (arrow) and negative for GS (arrowhead) in dogs. Immunohistochemistry using the avidin-biotin-peroxidase complex method, the chromogen 3,3′-diamino-benzidine, and Mayer’s hematoxylin as counterstain. Bars, 40 μm.
