Abstract

Objective: To evaluate the effect of tissue factor (TF) in extravascular migration of fibrosarcoma cells and hematogenous metastasis.

Methods: The expression of tissue factor in fibrosarcoma HT1080 cells was analyzed by flow cytometry. The extravascular migration of fibrosarcoma cells was observed in a constructed monolayer vascular endothelial cells and extra-cellular matrix model.

Result: Tissue factor was highly expressed in HT1080 cells. HT1080 migrated and passed through the monolayer vascular endothelial cells to the collagen gel in a time-dependent manner. Anti-TF antibody inhibited extravascular migration of fibrosarcoma cells and the inhibition was concentration-dependent (P<0.05).

Conclusion: Tissue factor may enhance hematogenous metastasis through extravascular migration of fibrosarcoma cells.
