Microvascular thrombosis and inflammation (thromboinflammation) are major causes of morbidity and mortality in critically ill patients with limited therapeutic options. Platelets are central to thromboinflammation, and microvascular platelet thrombi are...
The Vein‐Chip recapitulates CVST Virchow's triad and enables systematic characterization of venous thrombogenesis with respect to fibrin formation and platelet aggregation. Distinct from the arterial setting, platelets universally adhere across the entire CVS Vein‐Chip independent of stenotic geometry and flow disturbance. Intriguingly, fibrin propagates along with the flow direction, but exclusively deposits to the inner vessel wall. Upon inflammatory endothelial injury, fibrin deposition mirrors to the outer vessel wall, but still not in the lumen. Together, the Vein‐Chip promises future applications for personalized thrombotic assessment and monitoring.
Organ on Chips
In article number 2214179, Lining Arnold Ju and co‐workers, devised a novel, cost‐effective, and high‐throughput fabrication method for the creation of personalized vein‐chips, employing movable typing stereolithography and organ‐on‐chip technologies. This innovative chip accurately replicates an individual patient's unique anatomy and hemodynamics, thereby facilitating the investigation of clot formation in cerebral venous sinus thrombosis. The vein‐chip demonstrates significant potential for future personalized thrombotic assessment and monitoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
