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.

First claim

1 .- 25 . (canceled)

26 . 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 a small molecule, wherein the GM-CSF, the tumor antigen, or the immune response-promoting bioactive factor is incorporated into or coated onto said scaffold composition.

27 . The device of claim 26 , wherein said device further comprises an extracellular matrix (ECM) component.

28 . The device of claim 26 , wherein the GM-CSF, tumor antigen, or immune response-promoting bioactive factor is covalently linked to said scaffold composition.

29 . The device of claim 26 , wherein the tumor antigen comprises a biopsy-extracted antigen or antigens.

30 . The device of claim 26 , wherein the tumor antigen comprises a tumor cell lysate.

31 . The device of claim 26 , wherein the scaffold composition comprises a biodegradable polymer.

32 . The device of claim 26 , wherein the scaffold composition degrades at a predetermined rate based on a physical parameter selected from the group consisting of temperature, pH, hydration status, and porosity.
