Forty years of the Japanese Society for Biomaterials looking back at my term of office as the chairperson

The compatibility of artificial materials with living system, such as antithrombogenicity and antiimmunogenicity, has been an important issue in the field of the biomaterials researches at the early periods of the biomaterials research. After that, the bioabsorbable materials have been subsequently incorporated as biomaterials. As a result, biomaterial researchers started participating in the field of drug delivery system (DDS), and combining biomaterials and cells not only led to bioartificial organs, but also tissue engineering. The bioabsorbable biomaterials function as scaffolds for the cells and play an important role in the field of regenerative medicine researches. © 2019 Wiley Periodicals, Inc.
