Evaluation of PD-L1 expression in normal organs in a mouse peritoneal dissemination model. PD-L1 expression in normal organs, such as the lung, liver, spleen, and kidney of mice injected with PD-L1-AAV and control AAV particles on day 74 is shown. Red arrows indicate positive cells. Original magnification, x 400. Bar = 50 μm. The number of PD-L1-positive cells in normal organs. All values are presented as mean ± SE of 8 mice in both groups. Statistical significance was determined using unpaired Student’s t-test
