Angiogenesis in Wound Healing
Angiogenesis, the formation of new blood vessels from pre-existing, vessels is a crucial process for tumor growth and metastasis (Folkman 1990; Kaafarani, Fernandez-Sauze et al. 2009). The new vessels supply the tumor cells with nutrients and oxygen and ensure efficient drainage of metabolites. Under normal conditions, a tissue or tumor cannot grow beyond 1 to 2 mm in diameter without neovascul...
متن کاملOxygen in acute and chronic wound healing.
Oxygen is a prerequisite for successful wound healing due to the increased demand for reparative processes such as cell proliferation, bacterial defence, angiogenesis and collagen synthesis. Even though the role of oxygen in wound healing is not yet completely understood, many experimental and clinical observations have shown wound healing to be impaired under hypoxia. This article provides an ...
متن کاملRole of sex hormones in acute and chronic wound healing
The sex hormones oestrogen and testosterone are important mediators of wound repair. Oestrogen enhances wound healing by reducing inflammation and enhancing matrix production. However, in post-menopausal women, when oestrogen levels are decreased, wound healing is impaired and susceptibility to chronic non-healing wounds increases. Surprisingly, although the speed of healing is impaired, an imp...
متن کاملRole of angiogenesis and angiogenic factors in acute and chronic wound healing
Angiogenesis plays a crucial role in wound healing by forming new blood vessels from preexisting vessels by invading the wound clot and organizing into a microvascular network throughout the granulation tissue. This dynamic process is highly regulated by signals from both serum and the surrounding extracellular matrix environment. Vascular endothelial growth factor, angiopoietin, fibroblast gro...
متن کاملPathophysiology of acute wound healing.
Wound healing is a complex process that can be divided into at least 3 continuous and overlapping processes: an inflammatory reaction, a proliferative process leading to tissue restoration, and, eventually, tissue remodeling. Wound healing processes are strictly regulated by multiple growth factors and cytokines released at the wound site. Although the desirable final result of coordinated heal...
