a miniaturized hemoretractometer for Blood Clot Retraction testing
Small, 2016Co-Authors: Zida Li, Xiang Li, Brendan M Mccracken, Yue Shao, Kevin R Ward, Jianping FuAbstract:Blood coagulation is a critical hemostatic process that must be properly regulated to maintain a delicate balance between bleeding and Clotting. Disorders of Blood coagulation can expose patients to the risk of either bleeding disorders or thrombotic diseases. Coagulation diagnostics using whole Blood is very promising for assessing the complexity of the coagulation system and for global measurements of hemostasis. Despite the clinic values that existing whole Blood coagulation tests have demonstrated, these systems have significant limitations that diminish their potential for point-of-care applications. Here, recent advancements in device miniaturization using functional soft materials are leveraged to develop a miniaturized Clot Retraction force assay device termed mHemoRetractoMeter (mHRM). The mHRM is capable of precise measurements of dynamic Clot Retraction forces in real time using minute amounts of whole Blood. To further demonstrate the clinical utility of the mHRM, systematic studies are conducted using the mHRM to examine the effects of assay temperature, treatments of Clotting agents, and pro- and anti-coagulant drugs on Clot Retraction force developments of whole Blood samples. The mHRM's low fabrication cost, small size, and consumption of only minute amounts of Blood samples make the technology promising as a point-of-care tool for future coagulation monitoring.

interplay of platelet contractility and elasticity of fibrin erythrocytes in Blood Clot Retraction
Biophysical Journal, 2017Co-Authors: Valerie Tutwiler, Hailong Wang, Rustem I Litvinov, John W Weisel, Vivek B ShenoyAbstract:Abstract Blood Clot contraction (Retraction) is driven by platelet-generated forces propagated by the fibrin network and results in Clot shrinkage and deformation of erythrocytes. To elucidate the mechanical nature of this process, we developed a model that combines an active contractile motor element with passive viscoelastic elements. Despite its importance for thrombosis and wound healing, Clot contraction is poorly understood. This model predicts how Clot contraction occurs due to active contractile platelets interacting with a viscoelastic material, rather than to the poroelastic nature of fibrin, and explains the observed dynamics of Clot size, ultrastructure, and measured forces. Mechanically passive erythrocytes and fibrin are present in series and parallel to active contractile cells. This mechanical interplay induces compressive and tensile resistance, resulting in increased contractile force and a reduced extent of contraction in the presence of erythrocytes. This experimentally validated model provides the fundamental mechanical basis for understanding contraction of Blood Clots.
