Tissue engineering is a rapidly advancing field that is likely to transform how medicine is practised in the near future. For hollow organs such as those found in the cardiovascular and respiratory systems or gastrointestinal tract, tissue engineering can provide replacement of the entire organ or provide restoration of function to specific regions. Larger tissue-engineered constructs often require biomaterial-based scaffold structures to provide support and structure for new tissue growth. Consideration must be given to the choice of material and manufacturing process to ensure the de novo tissue closely matches the mechanical and physiological properties of the native tissue. This review will discuss some of the approaches taken to date for fabricating hollow organ scaffolds and the selection of appropriate biomaterials.
组织工程是一个快速发展的领域,在不久的将来很可能会改变医学实践的方式。对于心血管系统、呼吸系统或胃肠道等中空器官,组织工程可以提供整个器官的替代物,或恢复特定区域的功能。较大的组织工程构建体通常需要基于生物材料的支架结构,为新组织生长提供支撑和结构。必须考虑材料的选择和制造工艺,以确保新生成的组织与天然组织的力学和生理特性紧密匹配。本文将讨论迄今为止用于制造中空器官支架的一些方法以及合适生物材料的选择。
