Key Takeaway
Note that this narrative review lacks reported efficacy or safety data for ADSC-Exos in diabetic foot ulcers.

This narrative review examines the potential application of adipose-derived stem cell exosomes for treating diabetic foot ulcers and managing diabetes. The scope of the article focuses on these specific conditions without detailing the underlying clinical trials or observational studies that may have informed the discussion.

The authors indicate that critical methodological information was not reported. Specific data points such as the study population, sample size, intervention dosing, and primary outcomes are absent from the provided text. Because these details are missing, the review cannot quantify the clinical benefit or risk associated with this intervention.

Safety and tolerability profiles were also not reported in the source document. The authors do not provide specific adverse event rates or discontinuation data. Without these numbers, clinicians cannot assess the risk-benefit balance for patients considering this therapy.

The practice relevance remains unclear due to the lack of quantitative evidence. Readers should interpret this review as a qualitative overview rather than a source of definitive clinical guidance for diabetic foot ulcer management.

Diabetes is a major global public health challenge. Diabetic foot ulcer (DFU), one of its most severe complications, imposes a substantial economic burden and severely impairs patients’ quality of life. Current treatment strategies often yield suboptimal outcomes, underscoring the urgent need for novel therapeutic approaches. Adipose-derived stem cell exosomes (ADSC-Exos) have emerged as a promising cell-free therapy with significant clinical potential. This review integrates the mechanisms through which ADSC-Exos facilitate diabetic wound healing with the phases of wound healing. It elucidates that ADSC-Exos function by alleviating oxidative stress, modulating inflammation, promoting angiogenesis, stimulating cell proliferation and migration, and suppressing excessive fibrosis. Additionally, this study organizes insights into how delivery strategies based on smart materials (e.g., hydrogels and bioscaffolds) and the latest physical modalities can overcome bottlenecks in clinical translation. This review aims to provide an integrated perspective for developing next-generation DFU therapies.
