Mesenchymal stem cells (MSC) are bone-marrow derived cells, capable of multipotent differentiation into connective tissues including bone, tendon and cartilage. They are an attractive source for autologous cell-based treatments for a range of clinical diseases and injuries. MSCs have been demonstrated to possess an age-related loss of cellular functions including differentiation potential and proliferation capacity; with implications for stem cell therapies in older patients. Furthermore the reduction in differentiation potential could contribute to ageing and age-related disease. Biological aging is coupled with a progressive reduction in the regulation of cellular, tissue and organ interaction, resulting in senescence. The purpose of this study was to investigate the epigenetic, RNA and protein changes in ageing MSCs in order to understand the age-related functional and biological changes required for their applications in regenerative medicine.
