     materials that adhere to the endothelial cell (ec) lining of blood vessels may be useful for treating vascular injury. cell adhesion molecules (cams), such as endothelial leukocyte adhesion molecule-1 (e-selectin) and vascular cell adhesion molecule-1 (vcam1), modulate ec–leukocyte interactions. in this study, we mimicked cell–cell interactions by seeding cells on alginate hydrogels modified with antibodies against e-selectin and vcam1, which are upregulated during inflammation. ecs were activated with interleukin-1α to increase cam expression and subsequently seeded onto hydrogels. the strength of cell adhesion onto gels was assessed via a centrifugation assay. strong, cooperative ec adhesion was observed on hydrogels presenting a 1:1 ratio of anti-vcam1:anti-e-selectin. cell adhesion was stronger on dual functionalized gels than on gels modified with anti-vcam1, anti-e-selectin or the arginine–glycine–aspartic acid (rgd) peptide alone. anti-vcam1:anti-e-selectin-modified hydrogels may be engineered to adhere the endothelium cooperatively.
