Summary: This article introduces a one-step fabrication of a cell sheet-laden hydrogel (CSH) for the complete repair and regeneration of full-thickness skin defects. The results showed that CSH promotes wound closure and accelerates mature granulation and dermis formation within 14 days. This research provides guidance and strategies for the complete repair and regeneration of full-thickness skin defects and has great potential for tissue regeneration in clinical applications.

Summary: This study designed a double-crosslinked hydrogel for wound dressing using photocrosslinkable gelatin methacryloyl (GelMA) and sulfhydrylated chitosan (CS-SH). The resulting hydrogels showed a highly porous inner structure, enhanced mechanical properties, and moisture retention capacity. In vitro studies showed no cytotoxicity and promoted cell proliferation. The double-crosslinked hydrogel also exhibited antibacterial properties and accelerated full-thickness skin defect healing in animal experiments.

Summary: In this study, a novel biodegradable gelatin/sulfated alginate hybrid scaffold was introduced as a dermal substitute for accelerating the healing of full-thickness diabetic foot ulcers in a diabetic mouse model. The hybrid scaffold exhibited no cytotoxicity and promoted cell growth with increasing sulfated alginate content. The pathology results showed that the hybrid scaffolds-treated wounds had more appropriate epidermal layer formation, more homogeneous distribution of collagenous tissue, and lower immune cell penetration.

Summary: This study developed a novel multifunctional hydrogel, Pltm@CNPs/Gel, which incorporates platelet membrane camouflaged cerium nanoparticles into a gelatin methacryloyl matrix. The Pltm@CNPs/Gel hydrogel possesses anti-oxidative and anti-inflammatory properties and accelerates diabetic wound healing by promoting neovascularization, cell proliferation, and collagen fiber organization. The hydrogel shows potential as a therapeutic option for diabetic wound healing and as a diabetic wound dressing candidate.

Summary: Increasing cell seeding densities have shown an inverse relationship with shear viscosity and a reduction in storage moduli, leading to lowered printing pressures for gel extrusion. However, higher cell concentrations may negatively impact the structural properties of the extruded material.

Summary: Loading human umbilical mesenchymal stem cell (hUMSC) derived exosome mimetics onto hydrogel scaffolds promotes wound healing more efficiently than exosome-loaded hydrogels. Exosome mimetics can enhance the proliferation and migration of dermal fibroblasts, potentially through enriching mitochondrial-derived oxidative phosphorylation-related proteins. Thus, exosome mimetics have promising potential as candidates for exosomes.
