H – L , histological analysis of liver metastasis of tumor-bearing mice and treated group showed ( H ) tumor foci (indicated with a black circle ) of control tumor mice, and ( I ) anti-TIM3 mAb-treated tumor mice showed several tumor foci (indicated with several black circles ). J , the number of tumor metastatic foci into liver tissue section was determined by counting fifty high power field under × 400 magnification of each mouse of an experimental group (n = 3). Data represent mean ± SD. ∗ p < 0.05 (Unpaired two-tailed t -test). Infiltration of inflammatory cells into liver was observed and demarcated by ( K ) blue arrow indicated the moderate (not too severe) infiltration into control tumor-bearing mice, while ( L ) the green arrow indicated the severe inflammatory cell infiltration into the liver of anti- TIM-3 treated group. All data represent mean ± SD; n = 3.
