Furthermore, an EML4‐ALK‐positive NSCLC xenograft model is applied for the purpose of evaluating whether PD‐L1 inhibitor synergistically potentiates the antitumor effects in vivo....we constructed the murine pro‐B cell line Ba/F3, which stably expresses the exogenous EML4‐ALK fusion gene. As expected, in the NSCLC xenograft model, we observed that CER plus PD‐L1 inhibitor treatment and the CER group both significantly attenuated tumor growth compared with the control...
