At high magnification (x2.5) from right Fig. 2, Top image shows the circular osteons present in adult bone. Note the heterogeneity of the mineralization, with dark (low mineralization) and white osteons (higher mineralization). Red arrows and blue lines point of the circular and smaller osteons. Middle image shows the corresponding section seen in polarized light. Bottom image illustrates at 8 µm thin-section of May-Grünwald Giemsa staining, from endosteal (E) to periosteal (P) area, at high magnification (x10). Black arrows shows a limited bone cellular activity, with cavity filled with giant adipocytes. Illustrations will be available at high resolution.
