ibiTea—A Scientific Get Together

We are pleased to invite you to our 5th ibiTea meeting. Join us for an informative webinar presented by a leading scientist in the field of vascular research. Learn more about how shear stress affects Von Willebrand Factor biology, and then discuss your questions with this expert.

Going With the Flow—The Tale of Von Willebrand Factor

Presented by Dr. Tom McKinnon, Imperial College London, United Kingdom

ibidi VI 0.1 flow chamber slides were coated with collagen and perfused with whole blood drawn from a healthy volunteer, then perfused over the collagen surface at 1500s-1. Platelets were rendered fluorescent with DiOC6, and images were captured in real-time.

ibiTea Topic Outline

In our 5th ibiTea, Dr. McKinnon will talk about the structure and function of Von Willebrand Factor (VWF) and how shear-based assays have helped shape our knowledge of this critical hemostatic protein. VWF is a large multimeric plasma glycoprotein that is essential for normal hemostasis. Quantitative or qualitative deficiency of VWF leads to a bleeding disorder known as Von Willebrand's Disease. Conversely, elevated plasma levels, and the failure to process large VWF multimers, result in excessive thrombosis. VWF is stored in and secreted from endothelial cells, where its expression is partly controlled by shear stress. Once released from the endothelium, the conformation of the molecule is highly responsive to the shear forces encountered in the vascular system. Thus, the use of flow-based models is critical to understanding VWF biology.


Dr. Tom McKinnon, Imperial College London, United Kingdom

Dr. Tom McKinnon is a Senior Lecturer at Imperial College London, working in the field of thrombosis and hemostasis. His main focus is on the structure and function of Von Willebrand Factor and the clinical implications of abnormal VWF function. Much of his work relies on performing shear-based perfusion assays to examine blood coagulation and thrombosis in real-time.
