: The introduction of tissue engineering approaches for the repair and replacement of human body components extends the application and importance of synthetic materials (biomaterials). Implanted biomaterials frequently evoke inflammatory responses, and are subsequently responsible for implant failure. We have established a system that allows for the analysis and quantitation of cellular inflammatory responses in vitro using Real- Time Polymerase Chain Reaction (RT-PCR). The inflammatory responses of non-transformed murine macrophages (Raw 264.7) cells were analyzed after incubation with polymethylmethacrylate (PMMA) microspheres in the presence and absence of lipopolysaccharide (LPS) at 8hrs. Elevated cytokine production serves as an indicator of inflammatory responses, thus we monitored the levels of interlukin-1b produced. Furthermore, we demonstrate that the presence of a bacterial component and debris particles can work in concert to elevate cytokine production leading to inflammation.
