Bone tissue engineering has attracted increasing interest for its advantages in solving clinical bone defects problems. The tissue engineered bio-derived bone is a breakthrough for treatment of bone defects. This paper summarized three essential elements of bone tissue engineering, namely scaffold material, seed cell and osteoinductive factors. It is pointed out that the degradable cell scaffold biomaterials with bioactivity, porosity, and inorganic phase strengthening, and bionic simulation of the natural bone formation is the trend in bone tissue engineering in the future.
