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

Figure 1

The expression of PD-L1 on MMICs. (a) The left two scatter plots showed the ALDH⁺ cells identified in the B16-F0 melanoma cells by flow cytometry using the ALDEFLUOR kit. Only ALDH⁺ cells were gated for analysis of the percentage of PD-L1⁺ALDH⁺ cells. The right two scatter plots showed the percentage of PD-L1⁺ALDH⁺ cells in B16-F0 melanoma cells. (b) The expression of PD-L1 in ALDH⁺ B16-F0 melanoma cells.
