Fig 4. Metatarsal bones of C57BL/6J mice at 21 DPI exhibiting periosteal bone proliferation of woven bone.

Fig 4

(A) Periosteal bone proliferation (arrowheads) and few large multinucleated cells within scalloped lacunae (osteoclasts, arrows) along the superficial margin of the periosteal new bone, just deep to the periosteal lining. (B) Periosteal bone proliferation (arrowhead) and osteoclasts (arrows) are apparent along the cortical surface of the bone. (C) Metatarsal bone from a PBS-inoculated control mouse demonstrating normal periosteum (arrowhead).
