Figure 2. Cross-correlation matrix between gene expression datasets obtained for liver tissue and HepG2 cell line samples from different sources and harvested in our previous work in 2016 (Hep13, Liv13) and current work (Hep20, Liv20). The indices d1, d3 and d5 for Liv20 indicate the particular individuals (donors of postmortem liver samples). SRA datasets: Hep13 - SRX395473 (2013) and SRX390071 (2014), Liv13 - SRX267708 (2013).
