Huaier aqueous extract inhibits the formation of spheroids. (A) Colorectal cancer cells (T1 and T2 cells) were incubated with the Huaier extract for 14 days under spheroid-forming conditions. The size of the spheroids was then evaluated under a microscope. (B) Quantification of spheroid-formation with colorectal cancer cells treated as in (A). Bars denote the standard deviation. ^*P<0.05 vs. untreated cells.
