Development of chitosan and its derivative scaffolds for tissue engineering

BACKGROUND： Chitosan has an excellent performance, such as non-toxic, non-irritating, biocompatibility and biodegradability, which can promote adhesion and proliferation of a variety of tissue cells. Chitosan has become a research hotspot in the tissue engineering scaffold.
OBJECTIVE： To investigate the application development of chitosan and its derivative scaffolds in tissue engineering.
METHODS： A computer-based search of China Biology Medicine Database and PubMed was performed for articles related to chitosan and its derivative scaffolds published from 1989 to 2013. The keywords were “chitosan, scaffold, tissue engineering” in Chinese and English, respectively.
RESULTS AND CONCLUSION： There are several aspects about the major use of chitosan and its derivative scaffolds for tissue engineering. One is to act as a cell culture scaffold; the second is to act as a compound scaffold which is combined with other materials; and the third is to be used as a modified scaffold. Chitosan and its derivatives are a kind of natural polymer material which has unique biological activity. It has broad application prospects in tissue engineering research. To be combined with other biomaterials or to prepare modified scaffolds will be the future research focus of chitosan and its derivatives.
