Fig. 9

Bone regeneration evaluated by HE staining. Coronal HE stained sections in the calvarial defect region of different groups were taken 4 and 12 weeks post-operation. The dotted line indicates the boundary of the 6-mm defect. Blue wary lines designate newly formed bone, and asterisks point to residual scaffolds. Scale bars in lower magnification images represent 1000 μm, and scale bars in higher magnification images represent 250 μm
