Combination VSV-mIFNβ-NIS and anti-PD-L1 Ab treatment significantly decreases tumor burden in AML mice. Quantitative analysis of percentage of GFP-positive tumor cells in the single-cell preparations. (A) Representative flow data and (B) scatter plots of the percentage of C1498.GFP cells in the cell suspensions. Mean ± SEM is shown (n = 4-6 samples per group). *P ≤ .05. The unpaired Student t test was used. FSC-A, forward scatter.
