Extensive scar tissue formation often occurs after severe burn injury, trauma, or as one of complications after surgical intervention. Despite significant therapeutic advances, it is still a significant challenge to manage massive scar tissue formation while also promoting normal wound healing. The goal of this study was to investigate the therapeutic effect of bone mesenchymal stem cells (BMSCs) that were genetically modified to overexpress transforming growth factor-beta 3 (TGF-β 3 ), an inhibitor of myofibroblast proliferation and collagen type I deposition, on full-thickness cutaneous wound healing in a rabbit model...

In this study, we investigated whether post-burn itch in rats, after a full thickness burn, is correlated to the nervous reinnervation of the burn wound area. For this purpose, we determined scratching duration (expressed as sec/hr) at 24 hours, 2, 4, 8 and 12 weeks post-burn and combined this with immunohistochemistry for protein gene product 9.5 (PGP9.5) to identify all nerve fibers, calcitonin gene related peptide (CGRP) to identify peptidergic fibers, tyrosine hydroxylase (TH) for sympathetic fibers and growth-associated protein 43 (GAP-43) for regrowing fibers...

Although platelets are widely recognized as having a critical role in primary hemostasis and thrombosis, increasing experimental and clinical evidence identifies these enucleated cells as relevant modulators of other physiopathological processes including inflammation and tissue regeneration. These phenomena are mediated through the release of growth factors, cytokines, and extracellular matrix modulators that sequentially promote (i) revascularization of damaged tissue through the induction of migration, proliferation, differentiation, and stabilization of endothelial cells in new blood vessels; (ii) restoration of damaged connective tissue through migration, proliferation, and activation of fibroblasts; and (iii) proliferation and differentiation of mesenchymal stem cells into tissue-specific cell types...

Bacterial cellulose (BC)/acrylic acid (AA) hydrogel has successfully been investigated as a wound dressing for partial-thickness burn wound. It is also a promising biomaterial cell carrier because it bears some resemblance to the natural soft tissue. This study assessed its ability to deliver human epidermal keratinocytes (EK) and dermal fibroblasts (DF) for the treatment of full-thickness skin lesions. In vitro studies demonstrated that BC/AA hydrogel had excellent cell attachment, maintained cell viability with limited migration, and allowed cell transfer...

BACKGROUND: The long-term aesthetic appearance of scars is of great importance to patients. Biobrane (Smith and Nephew, Fort Worth, Texas), a biosynthetic skin dressing, is a successfully established dressing for the treatment of superficial wounds. A new silk barrier dressing (Dressilk; Prevor, Moulin de Verville, France) has also shown good results in wound healing. This study evaluated the long-term scar quality of superficial wounds treated with these dressings. METHODS: From February 2012 to May 2013, 11 patients with burns in need of skin grafting received donor site treatment...

Sanguisorba officinalis L. is widely used in China to treat various wounds, particularly burns. The present study was carried to evaluate the healing efficacy of a purified polysaccharide (SOP) from the roots of S. officinalis L. on burn wound models in mice. The results indicated that oral administration of SOP (50 and 200 mg/kg) significantly stimulated wound contraction and reduced epithelialization time as compared to control group, which might be mediated by promoting collagen synthesis as evidenced by an increase of hydroxyproline content...

It is more than a decade that amniotic membrane has been used as a wound dressing because of its anti-inflammatory, anti-microbial, anti-fibrotic, anti-scaring properties, as well as its pain relieving and epithelialization promoting features. However, amniotic membrane had limited applications because it needs to suture in surgery, is highly fragile, firmly adhere to the wound and may cause bleeding and pain when changing the bandage. This study investigated the possibility of development of a novel amniotic-based chitosan gel dressing as a potential wound repair substrate with marked efficacy...

Aerosols exist in the form of liquid or solid particles that stably suspending in air. Our previous studies have found that aerosol can accelerate chronic wound healing. However, the biological effects of aerosol in burn wound healing and the underlying molecular mechanism remain unclear. This study aimed to investigate the effects of aerosol on the healing of deep partial-thickness burn wounds and its regulatory mechanisms. By employing a self-controlled model of rats, we demonstrated that aerosol treatment not only increased the healing rate, but also improved the healing quality of deep partial-thickness burn wounds...

The evolved resistance of antibiotics exhibited by some dreaded clinical pathogens and formation of biofilms has caused life-threatening problems for patients with burns and other wounds. Here, in order to avoid antibiotic overuse, and thus decreasing the occurrence of antimicrobial-resistant bacteria, a theranostic wound dressing, composed of biocompatible UV-photocrosslinkable methacrylated gelatin (GelMA) encapsulating both antimicrobial and fluorescent vesicles, has been developed. The system can respond to the microbiological environment of the wound via a simple color change and antimicrobials release only when require and this is in essence passive as they do not respond to their local environments and benign bacteria, and only operates when pathogenic bacteria exist...

AIMS: Traumatic loss of skin, particularly in major burns, requires skin grafting to repair the tissue. For a large burn, where donor sites are limited, the skin graft may need to be expanded. In addition, rapid wound closure is a large factor in successful recovery and is usually achieved by debridement and skin grafting. Micrografting was introduced by Meek and involved dividing the skin into small pieces, allowing for up to a tenfold skin expansion. METHODS: We conducted a review of the literature, searched via Medline, Pubmed and Embase (from 1958 to June 2017), searching to identify studies and reports of micrografting...

Epithelial differentiation of adipose-derived stem cells (ADSCs) is mediated by sophisticated interactions of various molecular functions and biological processes, including transcriptional regulation. Runt-related transcription factor 2 (RUNX2) increases osteoblast and adipocyte differentiation of ADSCs. However, the role of RUNX2 in epithelial differentiation of ADSCs is unknown. We first showed that ADSCs possess the potential to differentiate into epithelial lineage. Then, we employed the effect of RUNX2 on epithelial differentiation of ADSCs...

Wound healing involves the integration of biological and molecular events and, in case of chronic wounds, the use of drugs can be associated to side effects. Therefore, there is a search for alternatives therapeutics that encompass minimal toxicity. The use of natural compounds is an attractive approach for treating inflammatory disorders, wounds and burns. In this context, thymol has antimicrobial, antioxidant and antiseptic properties and is a promising compound in wound healing and inflammation management...

BACKGROUND: Diagnosing the extremes of superficial burns and of full-thickness burns is straightforward. It is in the middle ground of partial thickness burns where the diagnostic difficulties emerge; it can take up to 3-5 days for signs of healing to appear. We hypothesize that cooling partial thickness burns and tracking the rate of rewarming will immediately reflect the condition of the burn: shallow partial-thickness burns that retain cell health and blood flow will rewarm rapidly, whereas deeper burns with damaged microvessels will rewarm slowly...
