Figure 2: 37H and Col37H were applied symmetrically and horizontally as a pair to the surface of the calvaria and covered with periosteum (A, Insert shows a cross-sectional drawing of the setting). Design of the analysis for bone mineral density and histological findings in the tunnels of the scaffolds (B). XCT image of ROI (Yellow square, 3.0 x 1.0 mm, top left panel), a sliced image (top middle panel), and slice thickness (top right panel, 1.0 mm) (C). Details of the ROI area for total bone density (bottom left), trabecular density (bottom left), and cortical density (bottom right).
