Matching sagittal micro-CT and histology images of explants taken from all animals at the end of the study. The histology was prepared using hard plastic embedding which was then stained with Sanderson’s Rapid Bone Stain and counterstained with Van Gieson stain. Sheep #1–4 display fully healed mandible bone grafts whereas the control animal (#5) shows non-union and a lack of pink/red stain seen in areas of undisturbed and fully healed bone. Instead, one sees blue-stained regions which indicate soft fibrous, cartilage tissues
