CTD inhibited the growth of AML cells. (A–D) HL-60, Kasumi-1, OCI-AML3, and HUVEC cells were treated with CTD as indicated for 72 h. Cell viability was measured using CCK-8 assay. (E) HL-60 cells were cloned in methylcellulose and treated with CTD as indicated. Two weeks later, colonies >50 μm in diameter were counted. The colony images were a representative of three independent experiments. Values are presented as the means ± SD. *p < 0.05, **p < 0.01, and ***p < 0.001 vs control.
