Trillions of Exosomes? Everybody Lies, Nobody Knows
7 hours ago
- There’s no sheriff in town. Exosome manufacturers self-report particle counts with no independent verification, no universal standard, and no regulatory oversight — meaning claims like “twice as many exosomes for half the price” can’t actually be checked.
- Identity isn’t content. Markers like CD9/63/81 confirm a vesicle is an exosome, but not what’s inside it. Without breaking vesicles open for RNA/proteomic analysis (an expensive step most companies skip), you’re buying a sealed “bubble” and trusting the label.
- Bigger numbers often mean smaller reality. Diluting a product inflates particle counts on paper while reducing true exosome concentration — a dynamic Dr. Park says pushed even the industry’s founding manufacturer to abandon “billions” language in favor of “”trillions”” just to stay competitive.
