Tissue engineering plays an increasingly important role in the repair and regeneration of tissues or organs.The scaffold material is an important part of tissue engineering,which can provide temporary mechanical support and necessary growth environment for the adhesion,growth,proliferation and differentiation of seed cells. According to their source,scaffold materials can be divided into three categories:natural materials,synthetic materials and composite materials.From the viewpoint of materials science,the research and application progress of various scaffold materials commonly used in bone,...
