PF inhibits HCC cell migration and invasion. (A and C) The effect of PF (20, 30 and 40 µM) on the migration and invasion abilities of Hep3B and Huh7 cells was examined by Transwell assays. (B and D) Quantification of the migration and invasion abilities of the Hep3B and Huh7 cells compared to the control. The chambers were stained with diff-quik stain kit, and the number of migrated or invaded cells were counted in five microscopic fields in each well at a magnification of ×200. **P<0.01, ***P<0.001, significant difference with regard to the control group. PF, Poncirus fructus; HCC, hepatocellular carcinoma.
