Abstract

Although limited, studies using mesenchymal stem cells (MSCs) on regenerative therapy have brought promising results, in the last few years. Some boundaries relies on the little knowledge we have about the basic biology of these cells, mainly regarding epigenetic control landscape in the dedifferentiation and multipotentiality cellular state. Amongst several epigenetic control mechanisms, DNA methylation and demethylation mechanisms are extremely relevant in this context. Understanding this scenario may contribute to improve the biological knowledge of what is currently known as health and human development and still be used in the process of cell and tissue regeneration. Aiming to better understanding this dynamic, human bone marrow mesenchymal stem cells will be demethylated by a DNA methyltransferase (DNMT)-1 inhibitor and the role of the DNMT-1 and TETs genes (methylation and demethylation genes) and their respective enzymes will be in vitro studied. This study aims to shed some light into the epigenetic regulation and its impact on global DNA methylation and demethylation and also in some specific genes, against stimuli that can affect the molecular and cellular microenvironment, such as DNA methylation by exogenous agent.
