A Narrative Review of Stem Cell-Derived Exosomes for Diabetic Nephropathy

Area of Science:

• Nephrology
• Regenerative Medicine
• Biotechnology

Background:

• Diabetic nephropathy (DN) is a primary driver of end-stage kidney disease globally.
• Stem cell-derived exosomes offer a novel therapeutic avenue for tissue repair by delivering bioactive molecules.
• Exosomes are nanoscale vesicles secreted by cells, carrying proteins, lipids, and nucleic acids.

Purpose of the Study:

• To review the therapeutic potential of exosomes from various stem cell sources for diabetic nephropathy.
• To synthesize current research on exosome-based therapies for DN, identifying findings and future directions.

Main Methods:

• A PRISMA-guided narrative review of preclinical and clinical studies.
• Literature search conducted across major scientific databases (PubMed, Web of Science, Scopus).
• Studies were evaluated for quality and methodological rigor, prioritizing high-impact research.

Main Results:

• Preclinical data indicate exosomes exert reno-protective effects, reducing inflammation, fibrosis, and oxidative stress in DN models.
• Exosomes derived from mesenchymal stem cells (MSCs) appear to provide superior therapeutic advantages compared to other stem cell sources.
• Ongoing clinical trials are assessing the safety and efficacy of stem cell-derived exosomes for DN.

Conclusions:

• Stem cell-derived exosomes represent a promising therapeutic strategy for diabetic nephropathy.
• MSC-derived exosomes show significant potential for treating DN, warranting further investigation.
• Optimization of exosome production, delivery methods, and therapeutic efficacy is crucial for clinical translation.
