GFAP immunostaining was found in astrocyte-like cells (Fig. 3E and F, respectively). Both type 1 (filamentous) astrocyte-like cells (Fig. 3F), with glial filaments lining the thin twig-like processes and type 2 (fibrous) astrocyte-like cells (arrowhead, Fig. 3F) containing thick branching processes, were present in both eDRG and aDRG NSCs.
