Abstract
Implantable materials having defined patterns of affinity regions for binding endothelial cells and providing for directed endothelial cell migration across the surface of the material. The affinity regions include photochemically altered regions of a material surface and physical members patterned on the material surface that exhibit a greater affinity for endothelial cell binding and migration than the remaining regions of the material surface.
