Foreign body giant cells (FBGCs) are a hallmark of the foreign body reaction caused by biomaterial implantation and are thought to contribute to biomaterial degradation and the duration of the response. Osteopontin (OPN) is a secreted, acidic matricellular protein with multiple phosphorylation sites that is highly expressed at sites of inflammation. OPN wildtype and knockout mice were implanted with poly(vinyl alcohol) sponges and explanted at 14 days. OPN knockout mice had more foreign body giant cells but fewer macrophages surrounding the implants than their wildtype counterparts. In an in vitro human FBGC assay, addition of soluble OPN was found to reduce macrophage fusion to giant cells. These are the first studies to show a direct inhibitory role of OPN in FBGC formation in response to implantation.

D007249 Inflammation A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
