Abstract:
BACKGROUND: Tissue engineering has a promising prospect in corneal transplantation. Scaffolds are always restricting the development of tissue-engineered cornea. OBJECTIVE: To analyze application of different seed cells and scaffolds, and to summarize the progress of tissue-engineered cornea in recent years.METHODS: First author searched literature from CNKI (2000/2010-10) and PubMed database (2000/2010-10). The key words are tissue engineering, corneal transplantation in Chinese or English. A total of 223 literatures were seized by computers, according to the inclusion criteria, papers concerning the advance, application and reconstruction of tissue-engineered cornea were analyzed. Finally, 33 papers were included for further analysis. The present study was to analyze the seed cells, scaffolds, organ building and clinical applications of tissue-engineered cornea and investigate the development direction in the future. RESULTS AND CONCLUSION: The results show that seed cells and scaffolds are the focus of the studies now. Corneal transplantation has a high success rate in organ transplantation since the immune privilege of eye and avascular cornea, and it will be able to be a tissue engineering organ that can be largely built, easy to transplant. Reconstruction of cornea has reached first base, but every kind of scaffold has certain drawbacks, so the next goal is to find an ideal scaffold material.
