Cell-Derived Exosome Therapy for Diabetic Peripheral Neuropathy: A Preclinical Animal Studies Systematic Review and Meta-Analysis

In this review, the authors discuss the promising role of exosomes from various cell sources as potential cell-free therapies for diabetic foot ulcers, highlighting their therapeutic benefits in wound healing and the challenges faced in their clinical application.

This meta-analysis found that ADSC-Exo therapy can enhance healing in both general and diabetic wounds by promoting neovascularization, improving epithelization and collagen fiber deposition, and reducing scar formation, suggesting significant potential for clinical and research applications.

This review discusses the potential of stem cell-derived extracellular vesicles for improving diabetic wound healing and highlights their mechanisms, limitations, and challenges, but provides no new clinical findings.

In this study, researchers found that gentamicin-loaded exosomes derived from a bovine leukocyte spleen extract significantly enhanced antimicrobial activity and tissue regeneration in infected diabetic wounds, showing potential as an effective therapeutic strategy for diabetic foot ulcers by improving infection control and promoting healing.

This study found that combining multiple low-dose exosome injections with NIR-II-responsive selenium telluride-mediated photothermal therapy significantly improved healing in diabetic mice with pressure ulcers, enhancing wound closure, hair follicle regeneration, and collagen remodeling compared to single high-dose exosome treatment.
