23 Jul Preparation method of high-activity artificial blood vessel stent
Abstract
The invention relates to a preparation method of an artificial blood vessel stent, particularly relates to a preparation method of a high-activity artificial blood vessel stent, and belongs to the technical field of tissue engineering. The preparation method comprises the steps of preparing a collagen/polycaprolactone nano-film by centrifugal spinning; winding the collagen/polycaprolactone nano-film into a tube; and then arranging a fiber material on the surface of the nano-film according to a certain direction to form an oriented fiber layer so as to prepare the artificial blood vessel stent.The artificial blood vessel stent prepared by the method is good in biological compatibility, collagen in blood vessels induces cell differentiation favorably to promote wound healing and acceleratecell proliferation, the biological activity of a blood vessel is high, and due to high degree of orientation of the blood vessel, ordered arrangement of cells is also facilitated.
