Histology and micro-CT appearance of FA sections from AG specimens at 12 weeks. A T0 specimen, B representative AG specimen at 12 weeks, and C corresponding micro-CT FA section at 12 weeks. Note the cortical (arrows) and cancellous (stars) bone formation surrounding the screw hole (SH) and the autograft (AG) at 12 weeks. The T0 specimen FA section exhibits a transversally cut screw because it was not removed since MRI was not performed for this animal. A, B Stevenel’s blue and picrofuchsin staining. Bone, cells, and autograft stained pink, blue, and brown, respectively. Scale bars: 200 µm
