Molecular characterization of stem and differentiated GBM cells. (A) GBM stem cell spheres were stained with PE and CD133-PE and then processed by flow cytometry. (B) Differentiated GBM stem cells were immunostained for GFAP followed by anti-rabbit alexa 488. Nuclei were stained with DAPI. Immunofluorescence was analyzed by confocal microscopy.
