Summary: Endothelial cells (EC) embedded within three-dimensional matrices (MEEC) when placed in the vascular adventitia control lumenal inflammation and intimal hyperplasia. Matrix-embedding alters endothelial immunogenicity in vitro. T helper (Th) driven host immunity is a major impediment for of allogeneic grafts. We therefore aimed to identify if modulation of T helper balance would affect immune compatibility and endothelial regulation of vascular repair in vivo.
