Abstract:

BACKGROUND: Tracheal damage and defects are commonly seen in clinical practice. It is difficult to performed tracheal anastomosis, which requires implantation of tissue-engineered trachea or artificial trachea to repair defects and improve its function. After implantation of tissue engineered trachea, the revascularization, immune rejection, infection, fibrous scar formation and rehabilitation function have been widely concerned.
OBJECTIVE: To review the progress of tissue engineered trachea seed cells, scaffolds, chondroplasia and vascularization, as well as the factors affecting the growth of tissue engineered trachea.
METHODS: First author searched PubMed database, CNKI and Google Scholars from January 2000 to April 2014, by using search terms of “Tissue engineering, Tracheal reconstruction, Trachea substitute, Scaffold revascularization, Seed cells, Transforming growth factor” in English and Chinese. A total of 140 articles relevant to tissue engineered trachea were screened, and 45 papers of them met the inclusion criteria.
RESULTS AND CONCLUSION: Tissue engineered trachea depends on the body’s living tissue or stem cells, which amplify and prolfierate on in vitro seed scaffolds, it is a technical method that repairs primary tracheal defects or in situ value-added end of the differentiation-inducing defects, thereby repairing the defect and achieve certain functions. The main factor of tissue engineered trachea is seed stem cells, tracheal scaffold, cartilage formation, vascular factors and growth factors that promote the regeneration of tissue engineered trachea.
