Abstract:
The normal ventilatory function is severely impaired by tracheal traumas, stenoses, tumors and some congenital diseases, which could result in tissue hypoxia and endangering the life of the patient. Resection and reconstruction of tracheal lesions is the most effective way to treat these diseases. At present, there is still no long-term safe and reliable method to achieve the reconstruction of long-segment trachea injury in clinical practice, and tissue-engineered trachea may be the solution to this situation. Cartilage, as one of the most important parts of tissue engineered trachea, plays a key role in providing mechanical support and maintaining the integrity of trachea. Tracheal tissue engineering cartilage regeneration process consists of several important parts, including the source of the cartilage cells, tissue engineering scaffold construction strategy and hydrogel composite scaffold material preparation, and the affecting factors of biological activity and application. This article reviews the new strategies of tissue engineered tracheal cartilage regeneration and the existing obstacles in order to provide reference for clinical practice.
