What they are
Extracellular vesicles produced when the multivesicular body fuses with the plasma membrane, releasing intraluminal vesicles into extracellular space. They circulate systemically and communicate with distant cells.
Longevity rationale
- Exosome composition changes with age.
- Young-donor MSC exosomes ameliorate aging phenotypes in rodent models.
- Non-cellular, potentially cheaper and safer than whole-cell therapy.
Current clinical reality
- FDA has not approved any exosome therapy.
- Numerous clinics offer IV exosome infusions for anti-aging, joint pain, and cosmetic purposes — outside evidence-based medicine and with unclear manufacturing standards.
- Serious adverse events have been reported with contaminated preparations.
Legitimate research directions
- Loading exosomes with defined therapeutic cargo (mRNA drugs, gene-editing components).
- MSC-exosome trials in wound healing, joint disease, and organ transplantation.
- Mesenchymal Stem Cell (MSC) Therapy — Intervention.
- Stem-Cell Tourism (Mexico, Bahamas, Panama) — Clinic.
