摘要:

医源性气管损伤虽然发生率较低但却危及生命,损伤范围大时需进行气管移植重建。目前气管移植重建手术仍是临床上亟待解决的难题之一。文章以气管移植的要素为出发点对目前组织工程气管的研究和临床现状进行综述。首先从力学支撑的角度总结了目前研究中应用的各类支架材料及其优缺点,其次从实现气管生理功能的角度着重阐述了构建组织工程气管所应用的生物材料和种子细胞的多样性,同时介绍了现阶段的研究热点,如各种生物活性分子的应用及其优势。气管移植的临床现状表明,构建组织工程气管要将多种要素进行多维度的整合,以期最大程度地模拟气管解剖结构和生理功能,实现对重建气管的力学支撑、快速血管化和气道上皮再生才能具备实际的临床转化价值和应用前景。

Abstract:

Iatrogenic tracheal injury is a life‑threatening problem in spite of the low incidence. Tracheal reconstruction is essential when the trauma is serious. At present, functional tracheal reconstruction needs to be tackled urgently in clinical practice. This review summarizes the current research and clinical status of the tissue‑engineered trachea based on the constituent elements of tracheal transplantation. First, the types of scaffolds and their advantages and disadvantages are summarized in the view of mechanical support. Second, the diversity of biomaterials and seeding cells used in research are emphatically expounded from the perspective of the physiological function of the trachea. Meanwhile, the hotspots of the current research, such as the application of various bioactive molecules are introduced in the paper. The clinical status of tracheal transplantation shows that multi‑dimensional integration of various elements is required in the construction of tissue‑engineered trachea, so as to maximize the simulation of the anatomical structure and physiological function of the trachea to achieve mechanical support, rapid vascularization, and epithelial regeneration of the airway. In this way, practical clinical value and application prospects can be generated.
