Abstract: | Periprosthetic bone loss is an important contributory factor for aseptic loosening of total joint replacements. It has recently been shown that osteoclast precursor cells are present in the wear particle-associated macrophage infiltrate found in the membrane surrounding loose implants and that these cells are capable of differentiating into osteoclastic bone-resorbing cells. Long-term co-culture of arthroplasty-derived macrophages and the rat osteoblast-like cell line, UMR-106, in the presence of 1,25(OH)2D3 results in the formation of numerous multinucleated cells that are positive for tartrate-resistant acid phosphatase and vitronectin receptor and capable of extensive lacunar bone resorption. The aim of this study was to determine the effect of cytokines/growth factors, known to be present in the arthroplasty membrane, on this process of osteoclast differentiation. During osteoclast formation, increased levels of macrophage colony-stimulating factor, interleukin-6, and to a lesser extent, interleukin-1beta, but not tumour necrosis factor alpha, were detected in the co-culture supernatants. Addition of neutralising antibodies to human interleukin-1beta or tumour necrosis factor alpha to the co-culture system did not inhibit osteoclast formation. In contrast, co-cultures to which neutralising antibodies to human macrophage colony-stimulating factor or interleukin-6 were added contained fewer cells positive for tartrate-resistant acid phosphatase and vitronectin receptor and formed significantly fewer resorption pits. Time-course studies showed that macrophage colony-stimulating factor and interleukin-6 increase osteoclast formation mainly in the early stages of osteoclast differentiation. These results indicate that the release of macrophage colony-stimulating factor and interleukin-6 by activated cells in the arthroplasty membrane is likely to contribute to pathological bone resorption associated with aseptic loosening by stimulating differentiation of mononuclear phagocyte osteoclast precursors into mature bone-resorbing cells. |
