Human periodontal ligament cells (hPDLCs) are known as ideal seed cells for the regeneration of periodontal tissues. Several factors (i.e., vitamin D 3 , luteolin, and 6-bromoindirubin-3'-oxime) have been shown to promote osteogenic differentiation of hPDLCs. In this study, we aim to investigate the effect of vitamin A on cell proliferation, migration, and osteogenic differentiation of hPDLCs. hPDLCs were cultured in osteogenic induction medium supplemented with different concentrations of vitamin A. Cell proliferation and migration assays were conducted after 24, 48, and 72 h of incubation, whereas osteogenic differentiation and osteogenesis-related gene expression were assessed after 21 d only. Our results demonstrated that 1-µM vitamin A stimulation exerted the most potent promotion effect on cell proliferation, migration, and osteogenic differentiation of hPDLCs. It also induced significant upregulation of osteogenic differentiation-related genes and mitochondrial complexes II and IV in hPDLCs. Vitamin A may serve as a promising potential candidate for periodontal tissue regeneration.
