Characterization of GBSCs derived from fresh surgical specimens. (a) Micrograph of GBSCs neurosphere incubated for 3 days, 7 days, and 14 days in vitro (DIV). A single GBSC grown in a define medium can form a neurosphere. Scale bar = 50 μm. (b)-(c) The expression of brain tumor stem cell markers; CD133 and nestin in neurospheres were confirmed by immunofluorescence. Scale bar = 20 μm.
