Abstract
Angiogenesis is an essential component of normal wound repair, yet the primary mediators of wound angiogenesis have not been well described. The current study characterizes the contribution of vascular endothelial cell growth factor (VEGF) to the angiogenic environment of human surgical wounds. Surgical wound fluid samples (n = 70) were collected daily for up to 7 postoperative days (POD) from 14 patients undergoing mastectomy or neck dissection. VEGF levels in surgical wound fluid were lowest on POD 0, approximating values of serum, but increased steadily through POD 7. An opposite pattern was noted for basic fibroblast growth factor-2. Fibroblast growth factor-2, which has been previously described as a wound angiogenic factor, exhibited highest levels at POD 0, declining to near serum levels by POD 3. Surgical wound fluid form all time points stimulated marked endothelial cell chemotaxis and induced a brisk neovascular response in the rat corneal micropocket angiogenesis assay. Antibody neutralization of VEGF did not affect the in vitro chemotactic or the in vivo angiogenic activity early wound samples (POD 0). In contrast, VEGF neutralization significantly attenuated both chemotactic activity (mean decrease 76 +/- 13%, P < 0.01) and angiogenic activity (5 of 5 samples affected) of later wound samples (POD 3 and 6). The results suggest a model of wound angiogenesis in which an initial angiogenic stimulus is supplied by fibroblast growth factor-2, followed by a subsequent and more prolonged angiogenic stimulus mediated by VEGF.

Cellular metabolism is at the foundation of all biological activities. The catabolic processes that support cellular bioenergetics and survival have been well studied. By contrast, how cells alter their metabolism to support anabolic biomass accumulation is less well understood. During the commitment to cell proliferation, extensive metabolic rewiring must occur in order for cells to acquire sufficient nutrients such as glucose, amino acids, lipids and nucleotides, which are necessary to support...

The transformation of fibroblasts to myofibroblasts plays a major role in fibrogenic responses during dermal wound healing. We show a contribution of calpain systems (intracellular regulatory protease systems) in vascular endothelial cells (ECs) to myofibroblast differentiation in wound sites. Dermal wound healing experiments in mice found that calpastatin (an endogenous inhibitor of calpains) is enriched in preexisting vessels but not in newly formed capillaries. Transgenic overexpression of ca...

Nitric oxide (NO) plays a pivotal role in the cutaneous healing process and a topical supplement of NO is beneficial for wound repair. In this work, a novel polyethylenimine (PEI) based diazeniumdiolate nitric oxide donor was prepared. The obtained polymer (PEI-PO-NONOate) was characterized by Fourier transform infrared (FTIR) spectroscopy, UV-vis absorption spectra, and nuclear magnetic resonance (NMR). The PEI-PO-NONOate polymer was stable under anhydrous conditions at different temperatures. ...

ABSTRACTIntroduction: Chemotherapy and radiation therapy are two mainstream strategies applied in the treatment of cancer that is not operable. Patients with hematological or solid tumor malignancies substantially benefit from chemotherapeutic drugs and/or ionizing radiation delivered to the site of malignancy. However, considerable adverse effects, including lung inflammation and fibrosis, are associated with the use of these treatment modalities.Areas covered: As we move toward the era of prec...

Abstract The enhancement of wound healing has been a goal of medical practitioners for thousands of years. The development of chronic, non-healing wounds is a persistent medical problem that drives patient morbidity and increases healthcare costs. A key aspect of many non-healing wounds is the reduced presence of vessel growth through the process of angiogenesis. This review surveys the creation of new treatments for healing cutaneous wounds through therapeutic angiogenesis. In particular, we di...

In this work, two kinds of hyaluronic acid (HA)-based hydrogels were fabricated: one is made from physical freezing-thawing of HA solution (HA1), and the other is from chemical cross-linking of HA and polysaccharide (HA2). They were applied to repair full-thickness skin defects with New Zealand rabbits as the test animals, using powder HA and cotton dress as the references. The wound starts to heal after wounds were disinfected with iodine followed by coating with HA2, HA1, HA and cotton dress (...
