Exosome therapy in Japan is provided privately rather than through routine insured care. How such products are categorized affects what providers may offer and under what conditions, and that framework differs from the one covering cell-based treatments. Asking a clinic to explain which category its treatment falls into is a reasonable starting point.
Source and handling deserve attention. Ask where the material originates, how donors or source tissue are screened, and what testing is carried out before use. Ask whether documentation of those checks can be shared with you. Clinics vary in how much they disclose, and a provider that answers plainly is easier to evaluate than one that does not.
Research continues and findings differ by application, so descriptions covering many conditions at once should be read carefully. Ask what evidence relates to your situation specifically, what would be assessed afterward, and at what interval. Bringing the proposed plan to your own physician before committing remains sensible, particularly when travel is part of the decision.
