Juglone could decrease cell viabilityof glioma stem- like cells in vitro. a Chemical structure of juglone. b Cell viability (U87, SHG62 and SHG66) decreased obviously after treatment with juglone at various concentrations (10, 20, and 40 μM) as compared to control (**P < 0.01). c The cell morphology (100×) of juglone-treated U87 showed that stem-like cell spheres formation decreased gradually after juglone treatment in a dose-dependent manner
