Tissue factor and PAR signaling in tumor progression

Tumor development depends on multiple reciprocal interactions of tumor cells with the host cell compartment. Tumor cells initiate TF-dependent crosstalks with the tumor microenvironment by releasing procoagulant microparticles, soluble cytokines and angiogenic growth factors. Conversely, the hemostatic system in the host compartment provides multiple circuits that regulate tumor growth and sustain angiogenesis. A combination of experimental models of spontaneous and transplanted tumor development and metastasis start to delineate the role of TF in tumor progression and identified potential therapeutic approaches to target the TF pathway.
