제목 PCL/HA Hybrid Microspheres as a Bone Substitute Material
초록 Polycaprolactone (PCL) is widely used as a bone substitute (graft) material, however, it poses poor tissue compatibility and osteoconductive capacity for bone regeneration. HA is a naturally produced non-immunogenic glycosaminoglycan and plays a significant role as a facilitator of osteogenesis for stem cells. We fabricated PCL/HA hybrid microspheres by a spray/precipitation method using a double nozzle spray. To investigate the bone regeneration behavior of PCL/HA microspheres, we used SD rat with a calvarial defect. From the animal study for bone regeneration using a calvarial defect model of SD rat for 4 and 8 weeks, it was observed from the analyses of micro-CT and Masson's trichrome staining that the PCL/HA hybrid microsphere group showed more enhanced bone regeneration than the PCL microsphere group, even after 4 weeks. PCL/HA hybrid microspheres can be a promising bone substitute material compared to the PCL microspheres without HA.
