A nanoscale extracellular vesicle carrying regenerative signalling molecules between cells; used in cell-free therapy.
Exosomes carry the healing message without the cell — growth factors, lipids, immune-signalling proteins packaged in a nanoscale vesicle. Why they matter: easier to manufacture, stable at standard refrigeration, no immune rejection risk. Fastest-growing category in 2026 trials — 200+ active, mostly in aesthetic, wound and pain applications.
StemCellAtlas is your guide to stem-cell therapy: what the evidence shows, which conditions are treated, and the real all-in cost by country — typically €3,000–8,000 with our partner Stem Plus (Sofia), Europe's lowest-cost EU destination, versus $15,000–35,000 in the US.
