Abstract

Gold nanoparticles (AuNPs) are a promising material for use in regenerative medicine due to their biocompatibility and easy functionalization with biomolecules including growth factors, DNA and peptides. In the present study, transmission electron microscopy indicated that the AuNPs were monodisperse and spherical in shape, with an estimated average diameter of 13 nm. And the cellular effects of AuNPs on the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) and the associated signaling pathways in cell differentiation were investigated based on histochemical analysis of alkaline phosphatase activity and mineralization, quantitative polymerase chain reaction, and western blotting. The results indicated that AuNPs enhanced the differentiation of hPDLSCs into osteoblasts, increasing their osteogenic transcriptional profile including alkaline phosphatase, osterix, collagen type I and runt‑related transcription factor 2 (RUNX2) and activating the p38 mitogen‑activated protein kinase (MAPK) signaling pathway. Furthermore, AuNPs increased the protein level of RUNX2, which is crucial for osteogenic differentiation. These results suggested that AuNPs stimulate the osteogenesis of hPDLSCs partially via activation of the p38 MAPK signaling pathway.
