Abstract

The purpose of this study was to examine the MAPK signaling pathways involved in regulation of HO-1 and the odontoblast differentiation markers during the odontoblastic differentiation for HDPCs. We evaluated cell growth by MTT assay and differentiation marker mRNA expression by RT-PCR. When the cells were treated with p38 inhibitor (SB203580, $10{\mu}M$), JNK inhibitor (SP600125, $10{\mu}M$), and ERK inhibitor (PD98059, $20{\mu}M$) for 7 days, cell growth and expression of HO-1 and differentiation makers were significantly decreased in HDPCs. Our results suggest that odontoblastic differentiation is positively regulated by HO-1 induction in HDPCs via ERK, JNK, and p38 signaling pathways. Thus, pharmacological HO-1 induction might represent a potent therapeutic approach for pulp capping and the regeneration of HDPCs.
