Figure 5. Macrophage depletion compromises DO-induced bone regeneration. Morphological histological analysis of the bone specimens was performed 14 days after removal of external fixers by micro-CT. (A, B) The density of the regenerative bone was assessed, shown by representative images (A), and by quantification (B). (C, D) Masson staining was also performed, shown by quantification (C), and by representative images (D). *p<0.05. NS: non-significant. N=8.
