In our experimental conditions, we found a correlation between the tumor cell ability to tightly interact (trapped cells) with the endothelial layer and the expression of selected adhesion molecules; in particular, α2-integrin, ICAM1, ICAM2 and β3-integrin expression levels correlated with the adhesion phase of the migration process (see also Supplementary Figure S2). This evidence concerns the gene ICAM2 and neoplasm.
