Claim 17:
18. A composition comprising:
spleen extracellular matrix in particulate form, wherein the spleen extracellular matrix comprises native growth factors retained from spleen tissue, the native growth factors including epidermal growth factor, vascular endothelial growth factor, and platelet-derived growth factor; and
lung extracellular matrix in particulate form, wherein the lung extracellular matrix comprises native epidermal growth factor retained from lung tissue, the native growth factors including epidermal growth factor;
