摘要： The invention provides method of fabricating a scaffold comprising a fluidic network, including the steps of: (a) generating an initial vascular layer for enclosing the chamber and providing fluid to the cells, the initial vascular layer having a network of channels for fluid; (b) translating the initial vascular layer into a model for fluid dynamics analysis; (c) analyzing the initial vascular layer based on desired parameters selected from the group consisting of a characteristic of a specific fluid, an input pressure, an output pressure, an overall flow rate and combinations thereof to determine sheer stress and velocity within the network of channels; (d) measuring the sheer stress and the velocity and comparing the obtained values to predetermined values; (e) determining if either of the shear stress or the velocity are greater than or less than the predetermined values, and (f) optionally modifying the initial vascular layer and repeating steps (b) - (e). The invention also provides compositions comprising a vascular layer for use in tissue lamina as well as a medical devices having a vascular layer and kits.

摘要： The present invention provides an in vitro blood vessel model for investigation of drug induced vascular injury and other vascular pathologies. The in vitro blood vessel model provides two channels separated by a porous membrane that is coated on one side by an endothelial cell layer and is coated on the other side by a smooth muscle cell layer, wherein said model is susceptible to the extravasation of red blood cells across said porous membrane due to drug induced vascular injury.
