Clinicians often experience delayed epithelialization in diabetic patients, for which a high glucose condition is one of the causes. However, the mechanisms underlying delayed wound closure have not been fully elucidated, and effective treatments to enhance epithelialization in patients with hyperglycaemia have not been established. Here we propose a new reagent, acylated homoserine lactone (AH...

The paraxial mesoderm of the neck and trunk of mouse embryos undergoes extensive morphogenesis in forming somites. Paraxial mesoderm is divided into segments, it elongates along its anterior posterior axis, and its cells organize into epithelia. Experiments were performed to determine if these processes are autonomous to the mesoderm that gives rise to the somites. Presomitic mesoderm at the ta...

wound healing has always been among important and crucial subjects in medicine. morphine dependency has also been a social and health problem in the middle east. this study was aimed to investigate the effects of morphine dependency on pro-inflammatory and fibroblast cell recruitment, as well as re-epithelialization and the revascularization processes involved in secondary intention wound heali...

PURPOSE To evaluate the role of prepared basic fibroblast growth factor (bFGF) and cytochrome c peroxidase (CCP) combination eyedrops in corneal epithelial healing of transgenic mice (B6(A)-Rpe(rd12)/J) after excimer laser photoablation. MATERIALS AND METHODS In this prospective study, 216 eyes of 108 mice underwent bilateral photorefractive keratectomy. We considered 4 groups: A, B, C, and D...

Re-epithelialization of cutaneous wounds in adult mammals takes days to complete and relies on numerous signalling cues and multiple overlapping cellular processes that take place both within the epidermis and in other participating tissues. Re-epithelialization of partial- or full-thickness skin wounds of adult zebrafish, however, is extremely rapid and largely independent of the other process...

PURPOSE To evaluate the effects of pirfenidone nanoparticles on corneal re-epithelialization and scarring, major clinical challenges after alkali burn. METHODS Effect of pirfenidone on collagen I and α-smooth muscle actin (α-SMA) synthesis by TGFβ induced primary corneal fibroblast cells was evaluated by immunoblotting and immunocytochemistry. Pirfenidone loaded poly (lactide-co-glycolide) (P...

PURPOSE To determine desmosomal glycoprotein isoform expression in bovine corneal, limbal, and conjunctival epithelium and desmosomal profile and distribution during corneal re-epithelialization. METHODS Immunofluorescence (IF) for desmosomal components on cryostat sections of fresh epithelia was supported by immunoblot analysis of tissue lysates. Wounded corneas maintained in organ culture w...

An essential feature of a healed wound is the restoration of an intact epidermal barrier through wound epithelialization, also known as re-epithelialization. The directed migration of keratinocytes is critical to wound epithelialization and defects in this function are associated with the clinical phenotype of chronic non-healing wounds. A complex balance of signaling factors and surface protei...

Third-degree burn wounds can cause devastating loss of functionality for patients. As such, platform technologies that allow effective wound management are needed. The purpose this study is to describe the use MatriStem™ urinary bladder matrix (UBM)-based products (MicroMatrix® + Cytal®) (MM+C) and a collagen glycosaminoglycan (GAG) product (Integra® Dermal Regeneration Template (DRT)) (DRT) in...
