At high magnification (x2.5) from left Fig. 2, top image shows the drifting osteons present in juvenile bone. Note the heterogeneity of the mineralization, with dark (low mineralization) and white osteons (higher mineralization). Red arrow and blue lines point of drifted osteons as shown in Robling et al. 1999. Middle image shows the corresponding section seen in polarized light. Drifting osteons exhibit a variation in the direction of transverse drift along their longitudinal axes, intermitent regions of concentric morphology and change in drift direction over time. Bottom image illustrates at 8 µm thin-section of May-Grünwald Giemsa staining, from endosteal (E) to periosteal (P) area, at high magnification (x10). Bone modeling is characterized by a formation (F) and resorption (R) at different location. Formation is mostly oriented throught the perioste and resorption in endoste, allowing the bone growth. Illustrations will be available at high resolution
