Pterostilbene attenuates the proliferation and differentiation of TNF-α-treated human periodontal ligament stem cells.

ABSTRACT: Periodontitis is a common chronic inflammatory oral disease. The objective of periodontal treatment is to control infection whilst regenerating damaged periodontal tissue. The present study aimed to determine the potential effects of pterostilbene (PTE), a representative stilbene compound, on the proliferation and differentiation of human periodontal ligament stem cells (hPDLSCs). Different concentrations (1, 5, 10 and 20 µM) of PTE were applied to hPDLSCs, after which Cell Counting Kit-8 and western blotting assays were performed to examine the protein levels of Ki67, PCNA, p-IκBα, IκBα, Bcl-2, Bax, cleaved caspase3. The effect of PTE on the release of inflammatory factors, including IL-1β, IL-6 and IL-10 was assessed by RT-qPCR. The apoptosis of TNF-α-induced hPDLSCs was evaluated by TUN
