Adipose tissue-derived stem cells (ADSCs) hold great potential for the stem cell-based therapy of cutaneous wound healing. Stromal cell-derived factor-1 (SDF-1) activates CXC chemokine receptor (CXCR)4+ and CXCR7+ cells and plays an important role in wound healing. Increasing evidence suggests a critical role for SDF-1 in cell apoptosis and the survival of mesenchymal stem cells. However, the f...

Prolonged healing and scar formation are two major challenges in the treatment of soft tissue trauma. Adipose mesenchymal stem cells (ASCs) play an important role in tissue regeneration, and recent studies have suggested that exosomes secreted by stem cells may contribute to paracrine signaling. In this study, we investigated the roles of ASCs-derived exosomes (ASCs-Exos) in cutaneous wound hea...

Autophagy is essential in physiological and pathological processes, however, the role of autophagy in cutaneous wound healing and the underlying molecular mechanism remain elusive. We hypothesized that autophagy plays an important role in regulating wound healing. Here, we show that enhanced autophagy negatively impacts on normal cutaneous healing process and is related to chronic wounds as dem...

Wound healing is a very complex process of interactions between different cells, growth factors, blood elements and extracellular matrix. Keloids represent one of the possible complications in the fundamental process of cutaneous wound repair. Despite all efforts, keloids remain a therapeutic challenge since no treatment is as yet considered 100% effective. Growth factors, discovered in the lat...

Sum mary Ecthyma gangrenosum is a well known cutaneous manifestation of Pseudomonas aeruginosa infections and is usually seen in immunocompromised patients. A previously healthy 5-month-old boy presented to our hospital with a complaint of an open inguinal wound. Physical examination revealed several ulcers surrounded by erythematous halos in bilateral inguinal regions. Pseudomonas aeruginosa w...

BACKGROUND Cutaneous sutures should provide good wound eversion, firm closure, and cosmetically elegant results. Simple running sutures are commonly employed in cutaneous surgery but may not always be effective in achieving wound eversion. OBJECTIVE We compared the cosmetic results of simple running nonabsorbable sutures with running horizontal mattress sutures in primary closures of facial d...

Skin wounds may lead to scar formation and impaired functionality. Remote ischemic preconditioning (RIPC) can induce the anti-inflammatory enzyme heme oxygenase-1 (HO-1) and protect against tissue injury. We aim to improve cutaneous wound repair by RIPC treatment via induction of HO-1. RIPC was applied to HO-1-luc transgenic mice and HO-1 promoter activity and mRNA expression in skin and severa...

The initial phase of wound repair involves inflammation, induction of tissue factor (TF), formation of a fibrin matrix, and growth of new smooth muscle actin (alpha-SMA)-positive vessels. In diabetes, TF induction in response to cutaneous wounding, which ordinarily precedes increased expression of vascular endothelial growth factor (VEGF) and alpha-SMA transcription, is diminished, though not t...

Cutaneous wound repair regenerates skin integrity, but a chronic failure to heal results in compromised tissue function and increased morbidity. To address this, we have used an integrated approach, using nanobiotechnology to augment the rate of wound reepithelialization by combining self-assembling peptide (SAP) nanofiber scaffold and Epidermal Growth Factor (EGF). This SAP bioscaffold was tes...
