Principal component analysis (PCA) of the gene expression datasets. The points of the scatter plots visualize the samples based on the top two principal components (PC1 and PC2) of gene expression profiles without (A) and with (B) the removal of batch effect. The colors represent samples from three different datasets, respectively. Landscape of immune cell infiltration in tumor immune environment of PDAC. Subpopulation of 22 immune cell subtypes (C) and proportional heatmap of the 22 TICs in each PDAC samples (D). E Intrinsic correlation of 22 infiltrating immune cells in PDAC. The cross-out cell indicates that the co-expression correlation between two genes is not significant (p > 0.05)
