Development of Scaffolds Used in Bone Tissue Engineering

As far as development of the bone tissue engineering is concerned, it is necessary for us to combine the material engineering and bioengineering adequately to design the materials on the molecular and cellular level. Therefore, the choice and preparation of extracellular matrix component (scaffold material) is an important and pivotal task in bone tissue engineering. To find a scaffold that can not only promote but also steer the attachment and proliferation of the cell is one of the focuses in recent investigation. In this paper, the correlative theory about bone tissue engineering is introduced and summarization of the scaffold materials is made.
