PD-L1 Promotes Self-Renewal and Tumorigenicity of Malignant Melanoma Initiating Cells

Figure 2

PD-L1 promoted tumorsphere formation. After co-culturing with anti-PD-L1, the sphere formation ability of (a) B16-F0 cells and (b) B16-F1 cells was impaired. (c) The chart showed the number of tumorspheres in each group. Each column represents the mean ± SE of three independent experiments.
