“…Our scRNAseq and scATACseq results are consistent with our previous gene array results using the endothelial-enriched RNA samples in bulk obtained from the same mouse PCL model . As shown in our bulk RNA data and other reports (Ajami et al, 2017;Jiang et al, 2014;Lee et al, 2017;Ni et al, 2010;Son et al, 2013;Wang et al, 2016;Wang et al, 2006), our singlecell data showed expected changes in many well-known flow sensitive genes including Klf2, Klf4,Nos3,Klk10,Angpt2,Ctgf,Bmp4,Timp3,Tgfb1,Thsp1,Col1a1,Tagln,Acta2,Cnn1,and Snai1. The current study also showed that d-flow induced inflammatory and proliferative pathways, consistent with our bulk RNA array result (Ni et al, 2010), further demonstrating the validity of our single-cell results. One of the major limitations of the bulk RNA study was the inability to ascertain the cell-types where the gene changes were occurring.…”
