Abstract With the global diabetes epidemic, diabetic foot ulcers (DFUs) have become a major health burden, affecting approximately 18 million people worldwide each year, and account for about 80% of diabetes-related amputations. Five-year mortality among DFU patients approaches 30%, which is comparable to that of many malignancies. Yet despite standard wound care, only about 30%–40% of chronic DFUs achieve complete healing within 12 weeks. This persistent failure shows that conventional dressings remain passive supports. They do not counteract underlying pathologies such as ischemia, prolonged inflammation, and infection. Recent advances in polymeric nanofiber scaffolds, particularly electrospun matrices,… More > Graphic Abstract

Abstract Regenerative medicine has attracted increasing attention across diverse organs, including the skin, musculoskeletal tissues, eye, and nervous system, where structural repair is limited. Among these, skin wound care is particularly urgent and challenging because diabetic ulcers, pressure injuries, and severe burns often resist standard dressings, debridement, and revascularization, resulting in infection, amputation, and high costs. Platelet-rich plasma (PRP) has gained value because platelets release coordinated growth factors and cytokines (e.g., platelet-derived growth factor, transforming growth factor-β, vascular endothelial growth factor, epidermal growth factor, fibroblast growth factor, and insulin-like growth factor-1) that modulate hemostasis, inflammation, angiogenesis,… More >

Abstract This commentary analyzes the effect of Exendin-4 on wound healing. After introducing information about the drug, considerations are added regarding its impact on this process. To accelerate wound healing, the drug’s combined effects with stem cells and other factors are examined, aiming to enhance and thus accelerate the process. Finally, the clinical potential of this drug’s effect is considered, not only for wound healing but also in other diseases. Therefore, reading this commentary may provide research perspectives that can stimulate the future reader’s thinking. More >

Abstract As the global prevalence of diabetes continues to rise, chronic diabetic wounds have become an important cause of amputation and death due to their protracted nature. In order to break through the limitations of traditional dressings, this study innovatively constructed a GelMA/HAMA-CS/PCL composite hydrogel-scaffold system containing chitosan based on biomaterials engineering and 3D printing technology. The system provides biomimetic ECM microenvironment through: photocrosslinked hydrogel layer (GelMA/HAMA-CS); Electrostatic spinning PCL film achieves mechanical strengthening and barrier protection. The chitosan component imparts long-term antibacterial activity, and the multi-materials cooperate to promote wound healing. In vitro antibacterial and… More >

Abstract Electrospinning has gained significant importance across various fields, including biomedicine, filtration, and packaging due to the control it provides over the properties of the resulting materials, such as fiber diameter and membrane thickness. Chitosan is a biopolymer that can be utilized with both natural and synthetic copolymers, owing to its therapeutic potential, biocompatibility, and biodegradability. However, producing electrospun chitosan is challenging due to its high solution viscosity, which often results in the formation of beads instead of uniform fibers. To address this issue, the spinnability of chitosan is significantly enhanced, and the production of continuous More >

Abstract Background: Impaired wound healing is one of the most well-known complications of type 2 diabetes mellitus. Experimental evidence suggested that treatment with Exendin-4, a glucagon-like peptide-1 agonist displaying a wide range of antidiabetic effects, can promote tissue regeneration. Objectives: Thus, this study aimed to examine the efficacy of topical treatment with Exendin-4 in accelerating wound healing in normoglycemic and hyperglycemic mice. Methods: For this purpose, two wounds inflicted on the back skin of 12 normo- and 12 hyperglycemic mice were injected intradermally with either saline solution or Exendin-4. Wounds were collected at the time of abrasion… More >

Abstract The main goal of the article is the creation and study of thermosensitive and wound-healing gelatin-alginate biopolymer hydrogels modified with humic acids. Their rheological properties, swelling and contraction behavior were experimentally investigated, elucidated using Fourier transform infrared spectroscopy and used to achieve the physiological melting point, which is necessary for successful drug delivery. It has been shown that in the gelatin-alginate-humic acid biopolymer hydrogels systems, it is possible to obtain a gel-sol transition temperature close to the physiological temperature of 37°C, which is important for drug delivery in the treatment of wounds. By changing the… More > Graphic Abstract

Abstract The exoskeleton of marine shrimp contains a natural, biocompatible polymer chitin, which is dumped as a waste. The study proposes the sustainable single-pot-extraction of chitosan from the waste and its use in the fabrication of wound-dressings, and thus leverage its piezoelectric, antioxidant, hypoglycaemic and medicinal properties in wound-healing. The Fourier transform infrared spectrum revealed that marine chitosan contains functional groups with N-O, O-H, and CO stretching. Scanning electron micrographs demonstrated the spherical and mesoporous structures of the extracted chitosan. X-ray diffraction analysis showed a semi-crystalline phase of chitosan particles with a mean size of 28.9… More >

Abstract The treatment of nonhealing and chronic cutaneous wounds still needs a clinical advancement to be effective. Both mesenchymal stem cells (MSCs), obtained from different sources, and their secretome derived thereof (especially exosomes) can activate signaling pathways related to promotion of cell migration, vascularization, collagen deposition, and inflammatory response demonstrating prohealing, angiogenetic and anti-scarring capacities. On the other hand, biodegradable biomimetic scaffolds can facilitate endogenous cell attachment and proliferation as well as extracellular matrix production. In this Review, we revise the complex composites made by biomimetic scaffolds, mainly hydrogels, and MSC-derived exosomes constructed for cutaneous wound More >

Abstract Diabetic patients often exhibit delayed or incomplete progress in the healing of acute wounds, owing to poor blood perfusion. Platelet-rich plasma (PRP) has attracted much attention as a means to improve wound healing, because it contains high growth factor concentrations. However, the burst-like release of PRP growth factors results in a short half-life of these therapeutic proteins, thus greatly limiting the therapeutic effect. In this study, we prepared PRP from human umbilical cord blood and developed an in situ photocrosslinkable PRP hydrogel glue (HNPRP) by adding a photoresponsive hyaluronic acid (HA-NB) into PRP. The HNPRP hydrogel… More >
