A Precision-Porous Polyurethane Material for In-situ Tissue-Engineered Vascular Grafts

摘要

Precision-engineered 40 μm porous PU can be tuned to match the mechanical properties of native blood vessels. Such material induces significant capillary ingrowth, via macrophage recruitment. The efficacy of these pro-healing vascular grafts will be studied in large animal models ( pigs and sheep).
