  • THIRD-GENERATION BIOMEDICAL MATERIALS AND REGENERATIVE MEDICINE

    Objective To summarize the developmental process of biomedical materials and regenerative medicine. Methods After reviewing and analyzing the literature concerned, we put forward the developmental direction of biomedical materials and regenerative medicine in the future. Results Biomedical materials developed from the first and second-generations to the third-generation in the 1990s. Regenerative medicine was able to help the injured tissues and organs to be regenerated by the use of the capability of healing themselves. This kind of medicine included the technologies of the stem cells and the cloning, the tissue engineering, the substitute tissues and organs, xenotransplantation and soon. Conclusion The third-generation biomaterials possess the following two properties: degradation and bioactivity; and they can help the body heal itself once implanted. Regenerative medicine is a rapidly advancing field that opens a new and exciting opportunity for completely revolutionary therapeutic modalities and technologies.

  • PROGRESS OF ALGINATE DERIVATIVES BASED ON BIOMEDICAL MATERIALS

    ObjectiveTo summarize the current research status of alginate derivatives based on biomedical materials, and analyze several key points as novel clinical products. MethodsThe general preparation and application methods of alginate derivatives based on biomedical materials at home and abroad were reviewed. The present status and problems were analyzed. ResultsThe derivation methods to prepare alginate derivatives include crosslink, sulfation, biological factors derivatization, hydrophobic modification, and graft copolymerization. With excellent bionic performance of structure and properties, many alginate derivatives are available for tissue engineering scaffolds, artificial organs, and drug delivery systems etc. However, more systematic applied basic research data should be collected and statistically analyzed for risk managements. ConclusionAlginate derivatives have good feasibility as novel medical products, meanwhile, systematic evaluation and verification should be executed for their safety, effectiveness, and suitability.
