DHM combination with NDP inhibits the ability of colony formation of liver cancer cells.

<p>(A) Colony formation capability assay with different treatments of DHM and NDP in HCC cells. The images were captured with a Nikon camera (Japan). (B) The clones were quantified and presented as a statistical figure. (C, D) The proliferation-toxicity of NDP or DHM in QGY7701, HL7702 and SMMC7721 cells with various drug concentrations and treatment durations were assayed using the MTT method (means ± S.D). (D) Proliferation and toxicity of different drug combinations were measured using the MTT assay (means ± S.D). Each experiment was repeated at least three times.
