The aim of this study is to investigate combined effects of mineral trioxide aggregate (MTA) and propolis on odontoblastic differentiation of human dental pulp stem cells (DPSCs) and to find a signaling pathway involved. Combination of MTA and propolis significantly up-regulated the expression of DSPP and DMP1, and facilitated a mineral nodule formation (p < 0.05). Treatments with MTA, propolis or combined increased the phosphorylation of extracellular signal-regulated kinases (ERK), one of mitogen-activated protein kinases signaling cascades during odontogenic differentiation of DPSCs (p < 0.05), and U0126, an inhibitor of ERK, decreased calcium deposits (p < 0.05). Combination of MTA and propolis promotes odontogenic differentiation and mineralization of DPSCs through ERK pathway.
