Abstract:Using micropipette aspiration technique, the authors investigated the viscoelastic properties of human hepatocytes and hepatocellular carcinoma (HCC) cells, and the experimental results were fitted with a threeelement standard linear solid model. Further, the authors investigated the change in viscoelastic properties of both hepatocytes and HCC cells by treatments with two drugs. Results showed: The elastic coefficients of HCC cells were obviously higher than the corresponding values of hepatocytes. After treatment with vinblastine and cytochalasin D, the viscoelastic coefficients of HCC cells were significantly lower than those of control. Under the action of vinblastine, the elastic coefficients of hepatocytes increased obviously than those of control, but the viscoelastic properties of hepatocytes treated with cytochalasin D had the same trend of decreasing as that of HCC cells. A breaf discussion was presented about these results.
Keywords:Hepatocellular carcinoma  Hepatocytes  Viscoelasticity  Vinblastine  Cytochalasin D
