| Outline of Final Research Achievements |
Recently, medical devices such as artificial organs and prosthetic implants are widely used for clinical practices. When these artificial materials are implanted into living body, the foreign body reactions are induced. The foreign body reactions against device implantation is different them against virus infection, and their biological mechanism have not been clarified yet. In this study, we analyzed the host responses against porous polyethylene scaffolds coated with MPC polymer, which is widely used as bioinert polymer, in the gene level. The results of gene level analyses suggested that the initial inflammation is strongly inhibited and delayed by MPC polymer coating.
