Histological images at higher magnifications of bony (A–G, Giemsa staining) and subcutaneous implants (H–I; Giemsa staining). (A) CPC after 12 weeks; (B) G-foam after 4 weeks; (C) osteoclast on foam particles (white arrow) in G-foam; (D) G-foam after 12 weeks; (E) G-foam after 20 weeks; (F) SG-foam after 4 weeks; (G) SG-foam after 20 weeks (remaining foam particles are embedded in the new bone); (H) subcutaneous G-foam implant (vessel formation is present (black arrow) and macrophages are on the cement (white arrows)); (I) subcutaneous SG-foam implant (macrophage on the foam is marked with a white arrow). Bars: 100 μm (A–E, G and H) or 200 μm (F and I).
