Andrew Hillman's 2026 structured review of published studies on stem cell exosomes and extracellular vesicles across the spine, brain injury, lung disease, knee osteoarthritis and other areas. We cover how early the evidence still is, why dose is reported in units that cannot be compared, and what the field needs next. FDA has not approved any exosome or MSC-EV product, and human use requires an IND or BLA. Hosted by Andrew Jonathan Hillman, Dallas, Texas.
