Identification, characterization and differentiation U87-GSCs and C6-GSCs. U87 and C6 gliospheres were cultured for 7 days, immunocytochemical staining of (A) the cancer stem cell marker, CD133, and (B) the neural progenitor marker, nestin, in U87-GSC and C6-GSC cells. (C) Following differentiation, the U87 and C6 glioma cells were immunostained with β-tubulin-III and GFAP. The fluorescent signals were detected and images were captured at x200 magnification. GSCs, glioma stem cells; GFAP, glial fibrillary acidic protein.
