We develop vessel-on-chip technology and approaches to create physiological models of the blood and lymphatic vasculature in vitro. Specific areas of investigation include the study of how chemical and mechanical signals, including uremic toxins, transluminal pressure, and shear and normal stresses impact blood vessel formation and function. Our platforms feature perfusable channels of endothelial cells within a soft, porous, 3D extracellular matrix. With these devices we are working to synthesize healthy and diseased vessels to study endothelial barrier function, angiogenesis, vasculogenesis, and lymphatic drainage. In addition, we are developing these platforms to include perivascular support cells to more closely recreate physiological conditions and to incorporate novel pumping systems to better recapitulate physiologic perfusion.

We use a combination of novel fabrication methods, biomaterials, and computational approaches to design, fabricate, and validate new systems for modeling the vasculature.
