Clot weight within the IVC was measured after IVC stasis was induced in tumor-bearing NSG and NSG-HA mice, as shown in Fig. 6E and F. With respect to TF-positive cancer cells, AsPC-1 (TFhigh) or MIA PaCa-2 (TFhigh) NSG mice had significantly more IVC clots than NSG-HA mice did. This evidence concerns the gene TF and cancer.
