(A) Viability of HT1080 cells treated with gradient doses of Huaier for 24, 48 or 72 h, as determined by MTT assay. The viability of the HT1080 cells was inhibited in a dose- and time-dependent manner. (B) Phase-contrast images revealing the morphologies of HT1080 cells prior and subsequent to treatment with 0, 4 or 8 mg/ml Huaier for 24 or 48 h. The HT1080 cells treated with Huaier appeared smaller and apoptotic, and had detached from the walls of the culture flask. ^**P<0.01 vs. control. Ctrl, control.
