Bio-synthetic material could replace soft tissue

Bio-synthetic material could replace soft tissue: "Soldiers whose faces have been marred by explosions could be among the recipients of a new biomedical material designed to permanently replace soft tissue. Developed at the Johns Hopkins University School of Medicine in Baltimore, PEG-HA is a composite consisting of synthetic and biological materials. Lab tests have indicated that it doesn't break down like pure biologicals, or get rejected like some synthetics."
