Growing evidence indicates that bone marrow-derived mesenchymal stem cells (BM-MSCs) enhance wound repair via paracrine. Because the extent of environmental oxygenation affects the innate characteristics of BM-MSCs, including their stemness and migration capacity, the current study set out to elucidate and compare the impact of normoxic and hypoxic(More)
Wnt and Notch signaling pathways are critically involved in relative cell fate decisions within the development of cutaneous tissues. Moreover, several studies identified the above two pathways as having a significant role during wound healing. However, their biological effects during cutaneous tissues repair are unclear. We employed a self-controlled model(More)
Granulocyte/macrophage colony-stimulating factor (GM-CSF) can accelerate wound healing by promoting angiogenesis. The biological effects of GM-CSF in angiogenesis and the corresponding underlying molecular mechanisms, including in the early stages of primitive endothelial tubule formation and the later stages of new vessel maturation, have only been(More)
The aim of this study was to explore the clinical value of the porcine acellular dermal xenograft (ADX) in combination with autologous split-thickness skin and pure autologous split-thickness skin grafting applied in deep fullthickness burns and scar wounds. A total of 30 patients with deep burns were randomly divided into experimental and control groups(More)
BACKGROUND As a common and important complication of diabetes, foot ulcers are characterized by high incidence, poor prognosis and variation in the clinical presentation. The current methods for classification of the diabetic foot are many, but few of them are validated owing to the lack of specific and accurate laboratory index. Thus, the development of(More)
To study the effect of porcine acellular dermal matrix (ADM) on the burn wound healing. Seventy healthy Wistar rats were inflicted with 2 cm second degree burn and divided into 2 groups; one group was treated with porcine ADM and the other with Povidone Iodine Cream. Biopsies were taken on day 1, 3, 5, 7, 10, 14, 21 for histopathological and biochemical(More)
Microvascular hyperpermeability followed by burn injury is the main cause of shock, and cardiovascular collapse can result if the condition is treated improperly. Our previous studies demonstrated that granulocyte/macrophage colony-stimulating factor (GM-CSF) clearly reduces microvascular permeability and protects microvessels against burn injury. However,(More)
The impairment of skin repair in diabetic patients can lead to increased morbidity and mortality. Proper proliferation, apoptosis and migration in keratinocytes are vital for skin repair, but in diabetic patients, hyperglycemia impairs this process. Dendritic epidermal T cells (DETCs) are an important part of the resident cutaneous immunosurveillance(More)
Hypertrophic scarring is a common dermal fibroproliferative disorder characterized by excessive collagen deposition. Prostaglandin E2 (PGE2 ), an important inflammatory product synthesized via the arachidonic acid cascade, has been shown to act as a fibroblast modulator and to possess antifibroblastic activity. However, the mechanism underlying the(More)
BACKGROUND Antisense nucleic acids are effective in inhibiting harmful or uncontrolled gene expression. We had previously proved that the antisense DNA to type I collagen could effectively inhibit the synthesis of collagen type I in cultured hypertrophic scar fibroblasts, suggesting a potential role in anti-scarring, but there are no published reports of(More)
