Description
The developmental potential of human pluripotent stem cells suggests that they can produce disease-relevant cell types for biomedical research. However, substantial variation has been reported among pluripotent cell lines, which could affect their utility and clinical safety. Such cell-line specific differences must be better understood before one can confidently use embryonic stem (ES) or induced pluripotent stem (iPS) cells in translational research. Towards this goal we have established genome-wide reference maps of DNA methylation and gene expression for 20 previously derived human ES lines and 12 human iPS cell lines, and we have measured the in vitro differentiation propensity of these cell lines. This resource enabled us to assess the epigenetic and transcriptional similarity of ES and iPS cells and to predict the differentiation efficiency of individual cell lines. The combination of assays yields a scorecard for quick and comprehensive characterization of pluripotent cell lines.

Description
DNA methylation is a mechanism of epigenetic regulation that is common to all vertebrates. Functional studies support its relevance for tissue homeostasis, but the global dynamics of DNA methylation during in vivo differentiation have not been worked out in detail. Here we report high-resolution DNA methylation maps of adult stem cell differentiation in mouse, focusing on 19 purified cell populations of the blood and skin lineages. Except for global demethylation in erythrocytes, observed DNA methylation changes were locus-specific and relatively modest in size. They frequently overlapped with lineage-associated transcription factors and their binding sites, suggesting that DNA methylation may protect cells from aberrant transcription factor activation. DNA methylation and gene expression provided highly complementary information, and combining the two enabled us to infer the blood lineage hierarchy directly from genomic data. In summary, our dataset and analysis demonstrate that in vivo differentiation of adult stem cells is associated with small but informative changes in the distribution of DNA methylation across the mouse genome.
