Multipotent periodontal ligament stem cells (PDLSCs) like other mesenchymal stem cells (MSCs) can give rise to bone, cartilage and fat tissues. They are relatively easily obtained during a third molar extraction and have been recently shown to have both good osteogenic potential and proliferation capacity. Therefore, they are promising candidates not only for periodontal regeneration but also for regenerative therapies in a broad range of bone diseases. However, the molecular mechanisms underlying osteogenic differentiation of PDLSCs are still not well understood with very limited information available regarding their epigenetic background and regulation. Such information is indispensable in order to safely apply PDLSCs in human clinical trials. In this project we aim to provide a substantial amount of data that will help to fill in the gap in our understanding of osteogenesis and mesenchymal stem cell differentiation. Firstly, the genome wide changes in DNA methylation and hydroxymethylation, chromatin accessibility and bone-specific transcription factor binding will be studied in PDLSCs during the process of osteogenic differentiation in order to appreciate their effect on bone-specific gene transcription. Secondly, the PDLSC populations with high and low osteogenic potential will be compared aiming to select potential epigenetic markers of preferential differentiation towards osteoblasts. And finally, in the second part of the project we will investigate the possibility of RE1-transcription factor (REST) being a novel regulator of osteogenic differentiation, the action of which could be modified by a plant polyphenol resveratrol. With its focus on tissue regeneration therapies the project aligns very well with the interest of both the School of Dentistry, Paulista University and the School of Dentistry, University of Birmingham and we expect it to develop into a long-lasting collaboration attracting other fellow researchers and postgraduate students.
