Each gene was expressed in both cell types with SVEP1 (Figure S1a) and ITGA4 (Figure S1b) more highly expressed in VSMCs and ITGA9 expression higher in endothelial cells (Figure S1c), in keeping with the previous atherosclerosis studies (Jung et al., 2021; Winkler et al., 2020). Here, ITGA4 is linked to atherosclerosis.
