Fig6. In vivo anti-tumor effect of an anti-human PD-L1 antibody in the humanized PD-L1 mouse model. (Tecentriq is a monoclonal antibody specific for human PD-L1)(A) PD-L1 humanized MC38 cells were subcutaneously implanted into humanized PD-L1 mouse model. Treatment of hPD-L1 antibody inhibited PD-L1 humanized MC38 tumor growth, demonstrating that the humanized PD-L1 mice are a good in vivo model for validating the efficacy of antibodies targeting human PD-L1. (B) Mean body weight of mice. All quantitative data are represented as mean ± SEM.
