The effects of the electrically polarized (HA) micro-granules/platelet-rich plasma (PRP) composite on new bone formation were examined. The composite gel was implanted into bone holes in rabbits. Histological examination was performed three and six weeks after the surgical operation. It was suggested that PRP alone could not induce new bone formation until 6 weeks after implantation. HA micro-granules with or without electrical polarization/PRP composte, especially the former, activated osteogenic cells, resulting in enhanced bone formation. It was confirmed that electrical polarization treatment of HA micro-granules can promote new bone formation, and that PRP works as a good carrier for them.
