Mouse Models of Spontaneous Thrombosis


Thrombosis comes in two flavours: VT: Venous thrombosis (with pulmonary embolism as possible results) and AT: Arterial thrombosis (with myocardial infarction or stroke as possible result). Venous and arterial thrombosis are a major source of morbidity and mortality worldwide and both are complex vascular diseases for which pathogenesis is incompletely understood. Animal models are fundamental in our effort to understand the disease and develop better therapy (“Holy Grail” an antithrombotic without bleeding risk as side-effect). Currently there are limited (venous thrombosis) or no (arterial thrombosis) technically reproducible or clinically relevant mouse models for these diseases.

Technology Overview

Researchers at the LUMC have developed a mouse model for VT via “humanizing” mouse coagulation via RNAi of the hepatic antithrombin (Serpinc1) and protein C (Proc) genes.
In addition, they have developed a mouse model for AT via RNAi of Proc in Apoe-/- mice. In initial studies organized and large thrombi superimposed on an aortic root atherosclerotic plaque were observed, a unique and novel finding. This model needs further optimization.

Potential applications would be in preclinical research of venous thrombosis and pulmonary embolism, and arterial thrombosis and myocardial infarction and stroke. 


Know-how on the VTE model is available for partnering and/or licensing. LUMC are seeking co-development partners to further optimize the AT model and/or study its response to drugs that are currently used in MI/stroke (lipid-lowering/antiplatelet drugs) and to those in current pipelines (PAR inhibitors, FXI inhibitors, others).
