HCC cells after insufficient RFA exhibited enhanced metastatic ability in vivo . SMMC7721 and SMMC7721-H cells were injected through tail vein of mice. (A) Lung metastasis was assessed. (B) The lung tissues were sectioned serially and stained with HE. Representative images of HE were shown (× 200). (C) The numbers of metastatic tumors were counted. Error bars represent the SEM of data obtained in three independent experiments. P value <0.05 was considered statistically significant; ***p < 0.001.
