Wound healing is known as one of the most complicated biological processes for injured skin caused by surgical, trauma, burns, or diabetic diseases, which causes a nonfunctioning mass fibrotic tissue. Recent reports have suggested that exosomes (EXOs) secreted this type stem cells may contribute to their paracrine effect. In study, EXOs were isolated from supernatant cultured adipose-derived (ADSCs) via ultracentrifugation and filtration. The EXO loaded in alginate-based hydrogel was used...
Functional wound dressing with tailored physicochemical and biological properties is vital for diabetic foot ulcer (DFU) treatment. Our main objective in the current study was to fabricate Cellulose Acetate/Gelatin (CA/Gel) electrospun mat loaded berberine (Beri) as DFU-specific dressing. The healing efficacy of fabricated dressings evaluated streptozotocin-induced rats. results demonstrated an average nanofiber diameter 502 ± 150 nm, tensile strength, contact angle, porosity, water vapor...
The present study aimed to evaluate the efficacy of cellulose acetate/gelatin/nanohydroxyapatite (CA/Gel/nHA) nanocomposite mats as wound dressing. dressings were prepared with electrospinning CA/Gel solutions containing 12.5, 25 and 50 mg nHA. evaluated regarding their water uptake capacity, morphology, tensile strength, vapour transmission rate, wettability cellular response L929 cell line. results showed that concentration nHA had a direct correlation porosity, contact angle, uptake,...
Abstract Combat or burn injuries are associated with a series of risks, such as microbial infection, an elevated level inflammatory response, and pathologic scar tissue formation, which significantly postpone wound healing also lead to impaired repair. Skin engineering for requires biomimetic dressing substrate ideal hydrophilicity, holding antioxidant antimicrobial properties. In addition, available bioactive specification is required reduce stimulate angiogenesis, improve this study, we...
