Tissue engineering a blood vessel: Regulation of vascular biology by mechanical stresses

Important to the tissue engineeping of a substitute blood vessel is an understanding of those faators which regulat vascular biology. A major factor in the mechanical environment imposed by the hemodynamics of the vascular system. In this the vascular endothelium play a critical role, and mver the past two deaades much has been learned about the influence of hemodynamics on vascular endothelial biology, to a large degree using cell culture to study the effects of flow and cyclic stretch. In our laboratory, such studies ape low being extended through the development of a model of the arterial wall involving the co‐culture of endothelial cells and smomth muscle cells. The development of such a model and its use in the study of endothelial cells and smmooth muscle the evolution of approaaheq to tissue engileeping a blood vessel.
