Figure 7

(a) Image of a grafted material interface (red arrow) and cortical bone. It is clearly shown the formation of cortical bone with osteocytes; (b) enlarged image of (a). Grafted material (red arrow). Osteocytes present in the gaps (green arrow); (c) well-formed Haversian system: note the arrangement of concentric lamellae, with the central channel of Havers (blue arrow). Osteocytes homogeneously distributed, demonstrating the usual architecture of cortical bone; (c) enlarged image of (d). In detail, the Havers channel, with endosteum (orange arrow) and red blood cells (white arrow).
