Figure 2From: Variable promoter methylation contributes to differential expression of key genes in human placenta-derived venous and arterial endothelial cellsUnsupervised hierarchical clustering (dendrogram) and heatmap of 1000 most highly variable probes in HPAEC and HPVEC samples. Despite evidence of variability in DNA methylation profile within each cell type, HPAEC and HPVEC samples are clearly discriminated according to methylation profile.Back to article page
