“…220 Differentiation of C6 cells with cholera toxin is also associated with increased expression of GFAP. 221 Other agents, including bFGF, 222 platelet-derived growth factor (PDGF), 222 RA, 223,224 histone deacetylase inhibitors (trichostatin A, sodium butyrate or valproic acid) 225,226 or panaxydol, 227 are also described to induce differentiation of the C6 glioma cell line. In addition, differentiation of C6 glioma cells with bFGF plus PDGF generates both neurons and glia in culture.…”
