Description

Technical Field

[0002] With the development of modern medicine, people pay more and more attention to vascular health, especially the research on vascular diseases, such as arteriosclerosis, vascular inflammation, and vascular blockage. These diseases can damage the structure and function of blood vessels, leading to obstructed blood flow, which in turn affects the normal function of various parts of the body and even causes serious health problems. In addition, some specific diseases, such as diabetes and hypertension, can also have adverse effects on human blood vessels and accelerate the aging process of blood vessels. In this case, it is particularly important to promote the regeneration and repair of blood vessels in damaged tissues or organs through artificial means in a timely manner. However, the current bioprinting technology is still a problem in achieving the efficiency and stability of artificial vascular endothelialization.

Synthetic polymer materials: such as Dacron, expanded polytetrafluoroethylene (ePTFE), polyurethane (PU), etc. These materials have good mechanical properties and durability, but they may cause fibrin and platelet deposition after contact with blood, leading to stenosis of the lumen and vascular occlusion.

[0005] 2. Animal-derived decellularized matrix materials: Animal blood vessels or mesentery are treated with enzymes, ultrasound or centrifugation techniques to become decellularized matrices, which are then prepared into tissue engineering artificial blood vessels. This method can retain some of the biomechanical properties of blood vessels, but is more likely to induce immune rejection reactions.

[0006] 3. Bio-coating technology: small molecules or surfactants are linked to the surface of artificial vascular materials to enhance the adhesion of endothelial cells to the inner wall of vascular materials, thereby improving the anti-thrombotic and anti-coagulation effects and improving long-term blood flow. However, for artificial tissue vascularization technology, factors such as the stability, uniformity and biocompatibility of the bio-coating are the core challenges.
