1. A cancer vaccine device comprising a scaffold composition comprising a polymer matrix and having open, interconnected macropores;
- a granulocyte-macrophage colony stimulating factor (GM-CSF) that recruits immune cells selected from macrophages, T-cells, B-cells, NK cells, and dendritic cells;
a tumor antigen; and
an immune response-promoting bioactive factor comprising an oligonucleotide, wherein the GM-CSF, the tumor antigen, or the immune response-promoting bioactive factor is incorporated into or coated onto said scaffold composition, wherein said device further comprises an extracellular matrix (ECM) component, and wherein the ECM component comprises an arginine-glycine-aspartate (RGD) sequence.

Abstract
A device that includes a scaffold composition and a bioactive composition with the bioactive composition being incorporated into or coated onto the scaffold composition such that the scaffold composition and/or a bioactive composition controls egress of a resident cell or progeny thereof. The devices mediate active recruitment, modification, and release of host cells from the material.
