Young small extracellular vesicles (sEVs) from adipose mesenchymal stem cells (ADSCs) rejuvenate aging animals. Treatment improved physical function, reduced frailty, and reversed epigenetic age markers, promoting healthier aging.
Area of Science:
- Gerontology
- Regenerative Medicine
- Cell Biology
Background:
- Aging increases frailty, disability, and mortality.
- Developing interventions to delay age-related decline is crucial.
- Adipose mesenchymal stem cells (ADSCs) are a potential source for regenerative therapies.
Purpose of the Study:
- To investigate the potential of young adipose-derived stem cell small extracellular vesicles (ADSC-sEVs) in mitigating aging phenotypes.
- To evaluate the impact of ADSC-sEVs on physical function, frailty, and biological aging markers.
Main Methods:
- Old animals were treated with sEVs derived from young ADSCs.
- Physical parameters (motor coordination, grip strength, fatigue resistance) were assessed.
- Biomarkers for oxidative stress, inflammation, senescence, epigenetic age, and metabolome were analyzed.
- MicroRNA content of sEVs was investigated.
Main Results:
- ADSC-sEV treatment improved motor coordination, grip strength, and fatigue resistance.
- Frailty was significantly reduced, with improvements in fur regeneration and renal function.
- Pro-regenerative effects were observed, alongside decreased oxidative stress, inflammation, and senescence markers.
- Treated animals showed a lower predicted epigenetic age and a youth-like metabolic profile.
Conclusions:
- Young ADSC-sEVs demonstrate significant rejuvenating effects in aged animals.
- Treatment promotes healthier aging by enhancing physical function and reducing biological aging markers.
- sEVs may hold therapeutic potential for combating age-related decline and frailty.
