[Application of silk fibroin scaffold in bone tissue engineering].

OBJECTIVE: To review the application of silk fibroin scaffold in bone tissue engineering. METHODS: The related literature about the application of silk fibroin scaffold in bone tissue engineering was reviewed, analyzed, and summarized. RESULTS: Silk fibroin can be manufactured into many types, such as hydrogel, film, nano-fiber, and three-dimensional scaffold, which have superior biocompatibility, slow biodegradability, nontoxic degradation products, and excellent mechanical strength. Meanwhile these silk fibroin biomaterials can be chemically modified and can be used to carry stem cells, growth factors, and compound inorganic matter. CONCLUSION: Silk fibroin scaffolds can be widely used in bone tissue engineering. But it still needs further study to prepare the scaffold in accordance with the requirement of tissue engineering.
