Abstract:

BACKGROUND: Cartilage tissue engineering provides new ideas and approaches for repair of cartilage defects, and how to obtain the ideal scaffolds for tissue engineering is the core and difficulty.
OBJECTIVE: To retrospectively analyze the material choice and preparation methods of tissue-engineered cartilage scaffolds.
METHODS: The first author searched PubMed, ELSEVIER SCIENCEDIRECT, Wanfang and CNKI databases (2000/2012) to retrieve relevant articles about materials and methods to prepare tissue-engineered cartilage scaffolds.
RESULTS AND CONCLUSION: Cartilage scaffold materials consist of natural biological material, synthetic polymer material and composite material. The following methods can be used to prepare scaffolds materials such as phase separation, solvent casting/particulate leaching, gas foaming technology, rapid prototyping technology and electrospinning. The collagen, agarose, alginate as hydrogel natural materials can provide adequate biocompatibility, proliferation, adhesion and hydrophilicity. Meanwhile, synthetic polymer composite scaffolds prepared by electrospinning can guarantee the mechanical strength, shaping requirements, porosity, and biodegradation of the scaffolds. Therefore, it will be more conducive to display the performance of the scaffolds if the natural materials are combined with synthetic polymer composite scaffolds using the embedded technology and surface modification technology.
