Abstract:

BACKGROUND: Repair of long tracheal injury has always been a major challenge in tracheal therapy. Tissue engineering tracheal decellularization technology can provide an effective treatment approach for long tracheal injury repair.

OBJECTIVE: To review the advantages and disadvantages of different acellular techniques in tissue engineered trachea and their application in tracheal replacement therapy.

METHODS: Using the terms “tissue engineered trachea, decellularization, tracheal reconstruction, tracheal replacement therapy” as key words, CNKI, Wanfang and PubMed database from January 2006 to November 2019 were analyzed and summarized.

RESULTS AND CONCLUSION: Long tracheal injury is mainly caused by tumor, trauma, stenosis, and infection. It requires tracheal replacement for airway reconstruction therapy, and the decellularized tracheal matrix prepared by acellular technology in tissue engineering research is an effective way for its treatment. Decellularization technology removes the immunogenicity of tissues or organs through physical, chemical and biological enzymes, and effectively retains the extracellular matrix of tissues and organs, providing a supportive environment for remodeling functional trachea. After surgery, patients do not need to rely on immunosuppressants. At present, there are cases of decellularization technology used in clinical tracheal transplantation, but patients have more complications after surgery, and its functions need to be further improved. With the development of decellularization technology, acellular methods have become more mature, sophisticated and diversified, providing directions and approaches for future clinical tracheal treatment. 

Key words: tissue engineered trachea, decellularization, tracheal replacement therapy, tracheal reconstruction, extracellular matrix, detergent combined with enzyme method, vacuum-assisted decellularization, sodium dodecyl sulfate
