| Research Abstract |
We have previously reported that cellular matrix laminin and inflammatory cytokine IL-1αgenes increased during periapical healing phase in a rat periapical periodontitis. In this study, we investigated the effect of these molecules to osteoblast that play a central role in bone formation. Our findings the enhancement of integrin α3 expression by IL-1α and the attachment of osteoblasts to laminin after stimulation with IL-1α suggest an important mechanism for adherence of osteoblasts in periapical healing.
