Abstract:

Mesenchymal stem cells (MSCs) with self-renewal and multipotential differentiation are thought to be the ideal seed cell in the repair and regeneration of orthopedic injury and degenerative disease. However, the same as any other somatic cells, MSCs are also aging upon a long-term culture which will have a negative effect in the treatment of disease. Thus it is important to understand the mechanisms of aging and look for the solution to delay or reverse the aging of MSCs. This review discuss the aging mechanisms of MSCs mainly from the telomeres and telomerase system, oxidative stress, silent information regulator protein, high glucose, Wnt/β-catenin signaling pathways activation, DNA damage and so on. We look forward to finding the solution to achieve the goal of delaying or reversing the aging process of MSCs.

Key words: Mesenchymal stem cells, Aging, Silent information regulator protein, Anti-aging
