Figure 8

Histologic morphology of the new bone at 8 weeks after implantation. In the central area, newly formed bone was more mature in the fibrin/ALN gel-implanted group than in the fibrin gel group. The arrow indicates the newly formed bone containing woven bone and lamella. Arrow head indicates the defect marginal site. Hb, host bone; Nb, new bone. Scale bar: 500 μm.
