Mesenchymal Stem Cells for Periodontal Tissue Regeneration in Elderly Patients

Abstract

Abstract Mesenchymal stem cell (MSC) grafting is a highly promising alternative strategy for periodontal regeneration in periodontitis, which is one of the primary causes of tooth loss in the elderly. However, aging progressively decreases the proliferative and differentiation potential of MSCs and diminishes their regenerative capacity, which represents a limiting factor for their endogenous use in elderly patients. Therefore, tissue regeneration therapy with MSCs in this age group may require a cellular source without the physiological limitations that MSCs exhibit in aging. In this sense, exogenous or allogeneic MSCs could have a better chance of success in regenerating periodontal tissue in elderly patients. This review examines and synthesizes recent data in support of the use of MSCs for periodontal regenerative therapy in patients. Additionally, we analyze the progress of the therapeutic use of exogenous MSCs in humans.
