Abstract

Mesenchymal stem cells (MSCs) exhibit a potent immunomodulatory and anti-inflammatory properties, which are very attractive for clinical use as prevention and/or treatment for several kinds of inflammatory disorders as graft-versus-host disease (GVHD), autoimmune diseases, renal injuries and others. In this context, a number of clinic studies have suggested that MSCs treatment may be safe and effective for preventing or treating of some inflammatory disorders. However, the outcomes of MSC therapies in multicenter randomized studies were so far disappointing. MSCs can be activated during inflammation and this appropriate activation can be a key to drive and enhance their therapeutic potential. In light of recent findings, it is speculated that promoter DNA methylation patterns (DNAm) could have a determinant function on gene activation and differentiation capacity of MSCs. Hence, in this present study, we intend to investigate if the DNA-methylation profile is modified in promoter regions of specifics genes in bone marrow derived MSCs during activation by inflammatory microenvironment.
