The study investigates the use of cellulose nanofiber scaffolds with sitagliptin and zinc sulfide nanoparticles to achieve scarless wound healing and hair follicle regeneration by targeting Dipeptidyl Peptidase 4 positive fibroblasts. The scaffold reduces fibrosis, improves collagen ratios, and enhances hair follicle generation. In vivo experiments on rats showed reduced skin fibrosis and increased new hair follicles, while in vitro studies indicated that the scaffold inhibits extracellular matrix secretion and fibroblast-to-myofibroblast conversion, promoting scarless healing. This approach could be a promising therapy for reducing scarring and enhancing skin regeneration.
