Development of chitin and its derivatives for tissue engineering

Objective:To investigate the present conditions and prospects of chitin and its derivatives use for tissue engineering. Methods:The literatures about the use in tissue engineering of chitin and its derivatives were widely reviewed, at one time, analysed the present conditions of them. ResultSrThere are two aspects about the major use of chitin and its derivatives for tissue engineering, one is act as a sustained release agent, the other is act as a biology scaffold material, and it had made an importan role in reconstruction of many kinds of tissues. Conclusion:Chitin and its derivatives were a kind of nature high polymer material which have distinctive biologic activity. It will be a wide prospect in study of tissue engineering. The focal point of chitin and its derivatives will focus on the compound materials.
