Research Advances on the Senescence Mechanism of Bone Marrow Mesenchymal Stem Cells Derived from Patients with Myelodysplastic Syndrome--Review / 中国实验血液学杂志

ABSTRACT

Emerging data have demonstrated that bone marrow mesenchymal stem cells (MSCs) play important roles in the progression of myelodysplastic syndrome (MDS). Experiments in vitro have showed that MSCs derived from MDS patients (MDS-MSC) exhibit the biological characteristics of cell senescence. Although the underlying mechanisms that regulate cell senescence need to be further elucidated, existing researches indicate that the mechanisms of MDS-MSC senescence have significant heterogeneity. Depth understanding of the underlying mechanisms involved in cell senescence of MDS-MSC are crucial to explore the potential therapeutic target of MDS. Therefore, this review summarizes research advances related with MSC senescence, such as MDS-MSC intrinsic changes in telomere shortening, DNA methylation status, oxidative stress and signal pathways regulating cell senescence in recent years.
