Effects of weaving parameters on the properties of completely biological tissue-engineered vascular grafts.

Tissue-Engineered Vascular Grafts (TEVGs) made of human textiles have been recently introduced and offer remarkable biocompatibility as well as tunable mechanical properties. The approach combines the use of Cell-Assembled extracellular Matrix (CAM) threads, produced by cultured cells in vitro, with weaving, a versatile assembly method that gives fine control over graft properties. Herein, we investigated how production parameters can modify the geometrical and mechanical properties of TEVGs to better match that of native blood vessels in order to provide long-term patency.
