Abstract:

BACKGROUND: Cartilage tissue engineering scaffold is a substitution for extracellular matrix, and there is a great significance on the shape and pore structure of the scaffold.
OBJECTIVE: To retrospectively focus on the fabrication technology of three-dimensional porous cartilage tissue engineering scaffolds.
METHODS: The first author searched PubMed, ELSEVIER SCIENCEDIRECT, Wanfang and CNKI databases (2000/2013) to retrieve relevant articles about the fabrication technology tissue-engineered cartilage scaffolds. The key words were “cartilage tissue engineering; scaffolds; fabrication” in English and Chinese, respectively.
RESULTS AND CONCLUSION: The fabrication technologies of three-dimensional porous cartilage tissue engineering scaffolds are as follows: Phase separation/freeze-drying, hydrogels, rapid prototyping manufacturing, electrospinning, solvent casting/particulate leaching, gas foaming. The current cartilage studies have demonstrated that the pore size has a significance on the regeneration of the cartilage tissue, the pore size ranging from 100-250 μm allows for the regeneration of bone and cartilage tissue. The scaffold fabricated by the solvent casting/particulate leaching and gas foaming technology at a pore size of 100-250 μm is suitable for the bone and cartilage tissue regeneration. To obtain the adequate biological and mechanical properties, researchers usually combine a variety of methods to fabricate the cartilage tissue engineering scaffolds.
