摘要：
Writ signaling has been implicated in increased bone formation by controlling mesenchymal stem cell or osteoblastic cell functions; however the role of Wnt signaling on cementogenesis has not been examined. Exposure to Wnt3a inhibited the expression of the osteocalcin (OCN) gene. This effect was accompanied by decreased gene expression of Runx2. Pretreatment with Dickkopf-1 attenuated the suppressive effects of Wnt3a on mRNA expression of Runx2 and OCN on cementoblasts. These findings suggest that canonical Wnt signaling inhibits cementoblast differentiation via regulation of expression of Runx2. Elucidating the role of Wnt in controlling cementoblast function will provide new tools needed to improve on existing periodontal regeneration therapies.
