Multiomic profiling of in vitro models of endothelial-to-mesenchymal transition reveals endothelial cell subtype is a major determinant of fidelity to observed states in atherosclerosis

Endothelial-to-mesenchymal transition (EndMT) is an example of endothelial cell (EC) heterogeneity which is commonly modeled in vitro to better understand driving mechanisms of disease proceses, including atherosclerosis. We used multi-modal single nucleus RNA sequencing (snRNA-seq) and ATAC sequencing (snATAC-seq) to analyze the diversity of ECs in vitro, divergent EC responses to known EndMT perturbations, and the ability of in vitro EC known EndMT models to recapitulate the in vivo 'omic profiles of cells observed in atherosclerosis. Overall design: ECs were treated with and without known EndMT-promoting perturbations and subject to 10x Genomics snRNA-seq and snATAC-seq. Please note that processed data files generated from both scRNA-seq and ATAC-seq raw data are linked to the corresponding *RNA sample records.
