WT1 and acute myeloid leukemia: The macroporous scaffold, consisting of crosslinked methacrylated PEG (MA-PEG) and methacrylated alginate (MA-alginate), was used to deliver granulocyte–macrophage colony stimulating factor (GM-CSF), the Toll-like receptor 9 agonist, cytosine-guanosine oligodeoxynucleotide (CpG-ODN) and one or multiple AML antigens, e.g., WT-1 to activate the immune response against leukemic cells, via activation of dendritic cells.
