Figure 2From: RNA-Seq gene expression profiling of HepG2 cells: the influence of experimental factors and comparison with liver tissueDissimilarity heatmap showing the clustering of the transcriptome samples based on the gene expression levels. Distance metric: 1 - Spearman correlation between the levels of the genes with RPKM > 0.1 in at least one sample; tree constructed using Ward linking; the numbers reflect pairwise correlation values.Back to article page
