⚠ Important — educational information only, not medical advice

EyeCyte provides educational and scientific information and does not provide medical advice, diagnosis, or treatment. Emerging regenerative and biologic technologies discussed on this website may be experimental, investigational, unapproved, or supported only by preclinical evidence. Patients should discuss medical decisions with appropriately licensed healthcare professionals.
Not an FDA-approved treatment unless explicitly stated. Except where a page names an FDA-approved product, the stem-cell, MSC, exosome, extracellular-vesicle, Wharton’s jelly and other biologic approaches described here are not FDA-approved for any eye condition. Research findings — especially laboratory and animal studies — are not proof that anything works or is safe in people.
Research-Use-Only (RUO): Research-Use-Only (RUO) materials referenced on EyeCyte are for laboratory research by qualified professionals only. They are not drugs, biologics or devices approved for human use, are not intended for administration to people, and are not intended to diagnose, treat, cure, mitigate or prevent any disease.
EyeCyte does not sell, offer, recommend or refer for treatment. Be cautious of any clinic offering unapproved stem-cell or biologic injections for the eye; the FDA has warned of serious harm, including blindness.

Full medical disclaimer · RUO policy · Medical review policy

"Exosome" is one of the most-searched terms in regenerative medicine — and one of the most loosely used. Scientifically, exosomes are a subtype of extracellular vesicle that originate inside cells; in practice, many products labelled "exosomes" are mixtures of particles whose contents are not fully characterised.

Research is not treatment. The studies summarized below are investigational. They are presented for education only, do not show that any approach is safe or effective in patients, and are not a recommendation. Unless stated as FDA-approved, none of these approaches is approved for this condition. RUO materials are not for human use.

Why an exosome is not automatically a treatment

A vesicle preparation is a biological material, not a medicine with established effects. Its effects — if any — depend on its source, manufacturing, purity, dose and route, and must be demonstrated in controlled studies.^[1]

Regulatory warning

The FDA has warned that there are no FDA-approved exosome products to treat diseases and that unapproved products have been associated with serious adverse events.^[2]
