Wound healing kinetics, tissue growth, cell proliferation (Ki-67) and angiogenesis (platelet endothelial cell adhesion molecule 1 and \u03b1-smooth muscle actin) were investigated. Messenger RNA levels related to angiogenesis (vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b-FGF)), profibrosis (platelet-derived growth factor A and transforming growth factor \u03b2), adipocyte expression (fatty acid-binding protein (FABP) 4 and peroxisome proliferator activated receptor \u03b3), and extracellular matrix remodelling (collagen I) were measured in wound tissues.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Wounds treated by VAC combined with fat grafting were characterized by cell proliferation, neoangiogenesis and maturation of functional blood vessels; they showed accelerated granulation tissue growth over the denuded bone compared with VAC- or foam dressing-treated wounds. Fat grafting alone over denuded bone resulted in complete necrosis. Expression of angiogenesis markers (VEGF and b-FGF) and adipocyte expression factors (FABP-4) was upregulated in wounds treated with VAC combined with fat grafting.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Fat grafting with VAC therapy may represent a simple but effective clinical solution for a number of complex tissue defects, and warrants testing in clinical models. Surgical relevanceThe combination of fat grafting and vacuum therapy represents a synergistic interaction of regenerative cells, hospitable wound matrix and stimulating micromechanical forces. It could accelerate complex wound healing through cell proliferation, neoangiogenesis and maturation of functional blood vessels. The efficacy of a multimodal wound healing approach is established in this experimental model; it could easily be translated into clinical trials of treatment for difficult wounds.<\/jats:p>\n
