Blood Vessel Growth Simulation (video) University of Utah Loading video... Caption This University of Utah computer simulation accurately predicted how tiny blood vessels, grow, branch and interconnect depending on the density of the "extracellular matrix" of collagen in which they grow. In the simulation, the network of blood vessels on the left grows more quickly than on the right because the collagen matrix is less dense on the left side of the simulation and more dense on the right side. The research is aimed at eventual treatments to provide blood supply to tissues damaged by diabetes and heart attacks and to skin grafts and implanted ligaments and tendons.
