Fig. 8

Metastatic burden and survival time of the tumor-bearing mice at different treatment groups. a One microscopic field of H&E-stained sections of livers in each group was illustrated as the sample. b The average number of metastasis colonies per microscopic field of the tumor-bearing mice’s liver 30 days after the cancer cells injection. The yellow arrows indicate a liver metastatic colony. c Mean percentage of the occupied space per microscopic field of the tumor-bearing mice’s liver 30 days after the cancer cells injection. d The survival time of tumor-bearing mice in different groups.
