Proposed mechanisms of tumor tissue factor (TF)-dependent metastasis. The full-length TF/factor (F)VIIa/FXa complex generates thrombin that activates platelets and generate fibrin. These activated platelets and fibrin inhibit the function of natural killer (NK) cells and attract monocytes/macrophage that helps establishment of premetastatic niche and tumor cell survival in metastatic niche.
