並列タイトル等イヌ下顎骨骨欠損モデルにおいて塩基性線維芽細胞増殖因子を固定させたα-リン酸三カルシウム多孔質体は骨再生を促進させる
一般注記The effect of porous alpha-tricalcium phosphate (-TCP) with immobilized basic fibroblast growth factor (bFGF) on bone regeneration was evaluated in a canine mandibular bone defect model. Identical bone defects were made in the canine mandible; six defects in each animal were filled with porous α-TCP with bFGF bound via heparin (bFGF group), whereas the other was filled with unmodified porous α-TCP (control group). Micro-computed tomography and histological evaluation were performed 2, 4, and 8 weeks after implantation. The bone mineral density of the bFGF group was higher than that of the control group at each time point (P < 0.05), and the bone mineral content of the bFGF group was higher than that of the control group at 4 and 8 weeks (P < 0.05). Histological evaluation 2 weeks after implantation revealed that the porous -TCP had degraded and bone had formed on the surface of -TCP particles in the bFGF group. At 8 weeks, continuous cortical bone with a Haversian structure covered the top of bone defects in the bFGF group. These findings demonstrate that porous -TCP with immobilized bFGF can promote bone regeneration.
