An Investigational Procedure Is Sold as Established: Questions About FDA Status
Say a clinic's flyer calls a stem cell injection "established" for knee pain. "Established" is a marketing word, not an FDA status.
Stem Cell Treatment Claims: How to Check FDA Status and Trial Registration
Imagine you're researching a stem cell treatment for a knee, back, or neurological condition. The clinic's website says the product is "FDA-registered" and links to a study on ClinicalTrials.gov. It sounds official.
What “FDA Registered” Can Mean for a Regenerative-Medicine Claim
"FDA registered" means a facility has told the FDA where it operates and what it makes there. It does not mean the FDA reviewed, approved, or confirmed that a specific product is safe or effective for a specific use. Those are two very different regulatory steps.
Expanded Access vs. Clinical Trials: FDA Pathways Explained
Expanded access and clinical trial participation are two different FDA pathways to an unapproved product, and confusing them is an easy, costly mistake. A clinical trial is a research study meant to generate evidence.
Investigational New Drug (IND) Language: What It Does—and Does Not—Signal
An Investigational New Drug (IND) application is a Food and Drug Administration (FDA) filing that lets a sponsor legally test an unapproved drug in humans.
FDA Approval, Clinical Trials, and Clinic Marketing: What Each Term Does—and Does Not—Mean
FDA approval, a clinical trial listing, and FDA registration are three different regulatory statuses, and clinic marketing often blurs them together. FDA approval means the agency reviewed safety and effectiveness evidence and licensed a product for a specific use.
Exosome Products: Regulatory Questions and Safety Boundaries
No exosome product is currently approved by the U.S. Food and Drug Administration (FDA) for sale in the United States. The FDA issued a public safety alert after receiving reports of serious adverse events tied to unapproved exosome products and separately warned that these products require agency…
Unproven Stem Cell Claims and Travel: Questions to Ask Before You Go
Evaluating an unproven stem cell claim before you travel means asking the same evidence, safety, and cost questions you'd ask at a clinic down the street — a discounted travel package or a plane ticket doesn't change what counts as proof, and distance can make problems harder to fix if something goes wrong.
An Exosome Offer Cites a Trial: Matching the Product to the Registry
Say a clinic's website or a social media ad offers an exosome treatment for joint pain, and it mentions a clinical trial or lists an NCT number to back up the claim.
Regenerative Medicine Testimonials: What They Cannot Establish
Updated September 2026 A testimonial can tell you that one person felt better after a regenerative medicine procedure. On its own, it cannot tell you whether the procedure caused that improvement, how likely it is to work for someone else, or how it compares to no treatment — because one story has…
Stem Cell Source in a Treatment Claim: What Was Actually Studied
By Regenerative Evidence Guide Editorial Team. Updated September 26, 2026. The source of a stem cell product is where the cells came from: your own body, a donor, cord blood, fat, amniotic fluid, or another tissue.
Exosome Research Headlines: Product Identity and Human Evidence Questions
If you saw an exosome headline and want to know what it means for a real person, start with two questions. First: what exact product was studied? Second: was it tested in people, and does anyone have the results? This guide walks you through both and ends with a checklist you can print. It does not recommend any treatment.
Regenerative Medicine Claims: A Reader’s Guide to Evidence, Uncertainty, and Questions
Most regenerative medicine claims — for stem cells, platelet-rich plasma (PRP), exosomes, or "biologics" — are not FDA-approved for the condition being advertised. The U.S.
Regenerative Medicine Terms Explained: Cells, Tissues, and Biological Products
Regenerative medicine terms like "stem cells," "tissues," and "biological products" are specific regulatory categories, not proof that a treatment works. A stem cell is a cell that can copy itself and turn into other cell types.
