Effects of scutellarein on viability of HT1080 cells. (A) Chemical structure of scutellarein (5,6,7,4′-tetrahydroxyflavone). (B) Toxicity of this compound on HT1080 cells, as determined by MTT assay (n=5). (C) Phase contrast images of the treated cells. HT1080 cells were treated with scutellarein (10 and 50 μm/l) or DMSO for 24 h. The values are the means ± SEM. ^**P<0.01.
