TranscriptomicsCellular aging can be monitored by DNA-methylation changes at specific CpG sites
Long-term culture associated changes need to be considered for quality control of cell preparations – especially in cellular therapy. Here we describe a simple method to track cellular aging based on continuous DNA-methylation changes at six specific CpG sites. This epigenetic signature can be used ...

TranscriptomicsReplicative senescence of mesenchymal stem cells causes DNA methylation changes which correlate with repressive histone marks
Cells in culture undergo replicative senescence. In this study, we analyzed functional, genetic and epigenetic sequels of long‐term culture in human mesenchymal stem cells (MSC). Already within early passages the fibroblastoid colony‐ forming unit (CFU‐f) frequency and the differentiation potential ...

TranscriptomicsAffymetrix SNP array data for different passages of mesenchymal stem cells.
Cells in culture undergo replicative senescence and unequivocally stop proliferation after a limited number of cell divisions. In this study, we have expanded mesenchymal stem cells (MSC) from human adipose tissue and analyzed genetic and epigenetic sequels. The subpopulation of highly proliferative...

TranscriptomicsMatrix Elasticity Does Not Affect Replicative Senescence or DNA Methylation Patterns of Mesenchymal Stem Cells [DNAm profiling]
Matrix elasticity influences differentiation of mesenchymal stem cells (MSCs) but it is unclear if these effects are only transient - while the cells reside on the substrate - or if they reflect persistent lineage commitment. In this study, MSCs were continuously culture-expanded in parallel either ...
