Histological images, stained with hematoxylin and eosin, of biomaterial implanting (A) after 4 weeks, displaying a small area of inflammatory tissue among the implanted biomaterial, (B) after 6 weeks, displaying mesenchymal cells growing into the implanted bone with a number of inflammatory cells, multinucleated cells around the demineralized bone matrix and osteoblasts in the lacuna, and (C) after 8 weeks, when the implanting area was fully covered with new-borne bone tissue, showing complete dissipation of inflammation (magnification, ×100).
