We measured the expression of key adhesion molecules and chemokines in atherosclerosis in BM CD45− Ter119− CD31− stromal cells (BMSCs) and CD45− Ter119− CD31+ endothelial cells (BMECs) isolated by fluorescence-activated cell sorting (FACS) from mice deficient in Apolipoprotein E (ApoE−/−) fed with chow diet or with HFD, to boost atherogenesis (Fig. 1a). Here, PECAM1 is linked to atherosclerosis.
