Core Tip

Core tip: Mesenchymal stem cells (MSCs) harbor the capacity to regenerate diverse tissues and can also perform key immunomodulatory functions. DNA methylation and demethylation are known to modulate stem cell maintenance and differentiation in embryonic stem cells. However, the role of DNA methylation and demethylation in MSC-based tissue regeneration and immunomodulation requires further investigation. In this review, we discuss how DNA methylation and demethylation function in multi-lineage cell differentiation and immunomodulation of MSCs based on previously published work. In addition, we discuss the implications of the role of DNA methylation and demethylation in MSCs for the treatment of metabolic or immune-related diseases.
