Supplemental Figure 3 from B7-H3 Expression in Merkel Cell Carcinoma–Associated Endothelial Cells Correlates with Locally Aggressive Primary Tumor Features and Increased Vascular Density

Supplemental Figure 3. Correlation between B7-H3/CD31 G-function co-localization index in MCPyV-negative MCCs. Plots showing the correlation B7-H3/CD31 G-function co-localization index for each primary MCPyV-negative MCC plotted against the frequency of associated malignancies (A) and lymphovascular invasion (B). G-function calculated according to a 1 pixel (1.57 �m) radius.
