Cell senescence abrogates the immunomodulatory therapeutic potential of human mesenchymal stem cells

ABSTRACT: In this study, we have addressed how cellular senescence influences the immunomodulatory potential of human mesenchymal stem cells (hMSCs). We induced cell senescence in a panel of bone marrow-derived hMSC samples by means of gamma-irradiation, and performed both gene expression and miRNA microarray analyses on the untreated and senescent samples. We also compared the gene expression profile of untreated and senescent hMSCs with those obtained from several hMSCs samples used in an ongoing allogeneic clinical study of Graft Versus Host Disease (GVHD), of which their therapeutic efficacy is known. We have identified several genes (PLEC, C8orf48, TRPC4, and ZNF14) differentially expressed in senescent hMSCs that are similarly regulated in hMSC samples that did not show a therapeutic effect in
