Application of polymer biomaterials in the tissue engineering Abstract BACKGROUND: The development of tissue engineering has provided a possibility for repairing and reconstructing tissues or organs. However, studies on biomedical tissue-engineered and polymer tissue-engineered materials need to be investigated. OBJECTIVE: To clarify the content of tissue engineering and the application of polymer material in tissue engineering from the point of biocompatibility。 DATA SYNTHESIS: The content of tissue engineering consisted of seeded cell inoculation, biomaterial implanting and cell transplantation. Allogenic, autogenous, and xenogenous tissues were in vitro broken into cells, and then reconstructed through inoculation and proliferation by gene reconstruction technique. Much attention should be focused on how to reconstruct tissue-engineered materials with materials and living cells, i.e. to reconstruct active materials with biological functions. Tissue-engineered materials should have the best interface reaction effect between material surface and cells. Therefore, the core of studying tissue-engineered materials is to design a device, which has chemical molecular level and three-dimensional molecular level cell/material mixed surface, and also has a three-dimensional molecular level appearance corresponding to biomechanical requirement. Polymer materials have good physical mechanical functions, and their molecular structures are closer to living body. Therefore, polymer materials are widely used as biomaterials and exert an important role in the field of tissue engineering. CONCLUSION: To study biomaterials with good tissue compatibility is the basis for tissue engineering development. Polymer materials are widely used in the tissue engineering due to their good property and molecular structure closer to living body.
