Host response to biomaterials
WebAlthough tissue-engineered bone scaffolds have biocompatibility, the host immune response is an inevitable stage after tissue-engineered bone implantation (Vishwakarma et al., 2016). The initial inflammatory response following biomaterial implantation aids in tissue repair and regeneration; however, persistent inflammation impairs the wound ... WebThe host response to biomaterials has been studied for decades. Largely, the interaction of host immune cells, macrophages in particular, with implanted materials has been considered to be a precursor to granulation tissue formation, the classic foreign body reaction, and eventual encapsulation with associated negative impacts upon device …
