Concurrent expression of Oct4 and Nanog maintains mesenchymal stem-like property of human dental pulp cells.

ABSTRACT: Human dental pulp stem cells (DPSCs), unique mesenchymal stem cells (MSCs) type, exhibit the characteristics of self-renewal and multi-lineage differentiation capacity. Oct4 and Nanog are pluripotent genes. The aim of this study was to determine the physiological functions of Oct4 and Nanog expression in DPSCs. Herein, we determined the critical role of an Oct4/Nanog axis modulating MSCs properties of DPSCs by lentiviral-mediated co-overexpression or co-knockdown of Oct4/Nanog in DPSCs. MSCs properties including osteogenic/chondrogenic/adipogenic induction differentiation was assayed for expression of osteogenic/chondrogenic/adipogenic markers by quantitative real-time RT-PCR analysis. Initially, we observed that the expression profile of Oct4 and Nanog in dental pulp cells, which exerted
