Abstract
A method, material, and kit for promoting neutrophils and monocytes to localize at a chronic ulcer site, promoting formation of a multi-layered cell structure in the ulcer site, promoting conversion of monocytes to macrophages, promoting secretion of the patient's own growth factors, promoting tissue proliferation and cell migration, promoting production and cross-linking of collagen at the chronic ulcer site, promoting growth of endothelial cells, promoting angiogenesis that was stalled at the chronic ulcer site, promoting formation of a vascular network and granulation, promoting oxygenation of the chronic ulcer site, and reducing one or more of purulent drainage, erythema, pain, warming, tenderness, induration, and bleeding at the chronic ulcer site.
