Figure 1. Effect of gossypetin on the proliferation of OSCC Ca9-22 cells. (A) Chemical structure of gossypetin. (B) Viability of Ca9.22 cells treated with various concentrations of gossypetin for 24 or 48 h as determined by the CCK-8 assay. (C) Representative photographs and quantitative analysis results of the colonization of Ca9-22 cells with or without gossypetin on soft agar. *p<0.01, **p<0.001 versus Control.
