摘要:
The artificial blood vessel comprises a cortex layer, a fibroblast layer, a smooth muscle cell layer, an endothelial cell layer and an inner cavity. According to the artificial blood vessel, the endothelial layer, the smooth muscle cell layer, the fibroblast layer and the cortex layer are orderly arranged in a three-dimensional space by utilizing integrated technologies of plasma spraying, electrospraying, electrospining, intra-mold pouring and 3D printing; anticoagulant activity of the artificial blood vessel is enhanced by adopting an anticoagulation factor; step-by-step induced differentiation of stem cells in the artificial blood vessel is realized by adopting a growth factor controlled release method; and the artificial blood vessel is cultured by a pulsatile reactor, so that the artificial blood vessel structurally and functionally simulates natural animal blood vessels and provides a corresponding substitute for vascular transplantation and repair.
