“…It has been well known that synthetic polymer materials containing PC group exhibit biocompatibility including blood compatibility (Sugiyama et al, 1995;Ohishi et al, 1997;Gong et al, 2005). Especially, the so-called MPC polymer, which is typically a copolymer of 2-methacryloyloxyethyl phosphorylcholine (MPC) with butyl methacrylate, has been reported as ideal non-thrombogenic and excellent biocompatible materials (Ishihara et al, 1990a(Ishihara et al, , 1990b(Ishihara et al, , 1991Ueda et al, 1992). This polymer was designed based on the inspiration from the outer surface of the cell membrane, i.e.…”
