Differentially expressed mRNAs in iPSC-ECs treated with e-cig. A Volcano plot of differentially expressed mRNAs is shown, where red and blue dots represent genes that are up- and downregulated, respectively, with at least a fold change of 2 and p value < 0.05. B Hierarchical clustering analysis showing differentially expressed mRNAs between non-treated (control) and e-cig (6.5 TPE)-treated group. C PCA of mRNA expression profiles is shown, with treated and untreated samples connected for each subject
