VWF and cancer: The ID-1 histoscores in cancer cells significantly correlated with MVC-CD34 (MVCs determined by immunohistochemistry for CD34; r=0.833, P<0.0001) and MVC-F-VIII (MVCs determined by immunohistochemistry for factor VIII-related antigen; r=0.742, P<0.0001); and ID-1 mRNA levels also correlated with MVC-CD34 (r=0.892, P<0.0001) and MVC-F-VIII (r=0.768, P<0.0001), as shown in Figure 6.
