Thrombus Canalization

Thrombus canalization is the formation of small channels through an organized blood clot, a remodeling process that can partially restore blood flow after vascular obstruction. As a thrombus matures, inflammatory cells, fibroblasts, and endothelial cells invade and reorganize its matrix; endothelial-lined passages may then develop within the clot and connect with the vessel lumen. In medicine, recognizing canalization helps explain how chronic venous or arterial thromboses evolve and why recanalized vessels may retain abnormal flow or remain narrowed. Its assessment supports interpretation of vascular imaging and informs understanding of thrombus resolution, persistent obstruction, and treatment outcomes.

The ear model of the hairless SKH1-Hrhr mouse enables intravital fluorescence microscopy of microcirculation and phototoxic thrombus induction without prior surgical preparation in the examined microvascular bed. Therefore, the ear of the hairless mouse is an excellent in vivo model to study the complex interactions during microvascular thrombus formation, thrombus evolution, and thrombolysis.

Intravital Fluorescence Microscopy to Study Microvascular Thrombus Formation

This video demonstrates the intravital fluorescence microscopy technique to study thrombus formation in a mouse model. The mouse is injected with a fluorophore-labeled polysaccharide to monitor blood circulation. Upon illumination with a high-intensity light, the phototoxic induction of an injury in the microvasculature of the ear leads to the formation of a thrombus, which is confirmed by visualizing the obstruction in the blood flow.

Thrombus Profiling Assay: A Microfluidics-Based Platform for Comprehensively Characterizing Biomechanical Thrombogenesis

This work describes a microfluidic assay that uses shear stress to trigger thrombus formation in blood and characterizes the thrombus by multiple dimensions of readout. The assay can measure the prothrombotic tendency of blood samples, and is thus useful in disease diagnosis, drug discovery, as well as basic mechanistic studies related to thrombosis.

Source: Kim, D., et. al. Combined Near-infrared Fluorescent Imaging and Micro-computed Tomography for Directly Visualizing Cerebral Thromboemboli. J. Vis. Exp. (2016)This video demonstrates visualization of cerebral thrombus in mice using micro-computed tomography (micro-CT) imaging. A cerebral thrombus mouse model is injected with fibrin-targeted gold nanoparticles acting as a contrasting agent. The mouse is placed on the bed of a micro-CT machine, and images are acquired from multiple angles.
