In the last few years it has become clear that, in addition to soluble molecules such as growth factors and cytokines, cells use extracellular vesicles (EVs) for intercellular communication. For example, EVs derived from cancer cells interact with endothelial cells, thereby affecting angiogenesis and metastasis, two essential processes in tumor progression. In most experiments, the interaction of EVs with target cells is investigated under static conditions. However the use of dynamic flow conditions is considered more relevant, especially when studying EV uptake by endothelial cells. Here, we describe the use of a perfusion system to investigate the interaction of (tumor) EVs with endothelial cells under dynamic flow conditions.
