ABSTRACT
<p><b>OBJECTIVE</b>To investigate the inhibitory effects of recombinant human endostatin (rh-ES) on cell adhesion, metastatic potential and invasiveness of hepatocellular carcinoma HCCLM6 cells in vitro.</p><p><b>METHODS</b>The changes in the cell proliferation status of HCCLM6 cells treated with different concentrations of rh-Endostatin in vitro was measured with MTT assay, and their invasiveness and migration were assayed using transwell cell culture chamber. The cell adhesion assay was carried out on 96-well plate precoated with matrigel.</p><p><b>RESULTS</b>Rh-ES showed inhibitory effect against the proliferation of HCCLM6 cells after a 72-h treatment. The adhesion, metastatic potential and invasiveness of the cells were obviously inhibited by rh-Endostatin in a dose-dependent manner.</p><p><b>CONCLUSION</b>Rh-ES inhibits the adhesion, invasiveness and migration of hepatocellular carcinoma cells in vitro, and the mechanism needs further investigation.</p>
