Figure 2From: Relating hepatocellular carcinoma tumor samples and cell lines using gene expression data in translational researchSpearman correlation between HCC tumors and HCC cancer cell lines (a) individual pairs (b) grouped by cell line. In the heatmap, each row represents a tumor sample; each column represents one HCC cell line. The correlation level is represented by color: higher correlation shown in red, lower in yellow. In the boxplot, each dot represents the correlation between one tumor sample and one cell line and the red line is the median.Back to article page
