What Questions Should You Ask Before Choosing a Stem Cell Clinic?

The gap between what's FDA-approved and what's marketed as "stem cell therapy" in the U.S. is wide — and it's the single biggest source of patient risk in this field. This article lays out the specific questions patients and caregivers should ask before agreeing to any stem cell treatment, drawn from FDA consumer guidance, an academic stem cell therapy center's pre-treatment checklist, and a national patient-safety resource, so readers can walk into a consultation prepared rather than persuaded.

Start With the Single Most Important Question: Is This FDA-Approved or a Registered Trial?

Only a small number of stem cell products are FDA-approved in the U.S. today, and they are overwhelmingly blood-forming (hematopoietic) stem cell products used for specific blood cancers and disorders — not the injectable "stem cell therapy" offered for joint pain, autoimmune conditions, or anti-aging at many private clinics. If a clinic is offering something else, ask directly: is this treatment FDA-approved for my condition, or is it part of an FDA-overseen clinical trial? The FDA has been explicit on this point: simply appearing in the ClinicalTrials.gov database, or a firm being "registered" with the FDA, does not mean a product is legally marketed or has been reviewed for safety and effectiveness. Ask the clinic to show you exactly where their treatment falls on that spectrum, and verify it yourself before proceeding.

Ask About the Cells Themselves

A legitimate provider should be able to answer, in specific terms, three things: what tissue the cells come from (your own bone marrow or fat tissue, or a donor source like umbilical cord tissue), what processing the cells undergo between collection and injection, and whether that processing goes beyond what regulators classify as "minimal manipulation." Minimally manipulated, same-day procedures using a patient's own cells face a different regulatory bar than products that are expanded, combined with other substances, or used for a purpose unrelated to their normal function — and that distinction is central to whether a treatment is legally marketed. A clinic that can't or won't explain this clearly is a warning sign.

Ask About the Physician's Training and the Evidence Base

Ask what specific training and licensing the treating physician has in regenerative medicine, and ask to see published, peer-reviewed evidence for your specific condition — not just patient testimonials or before-and-after photos. Reputable centers acknowledge the limits of current evidence and can point to specific studies with real patient numbers. Testimonials alone, however compelling, are not evidence, and academic stem cell centers explicitly warn patients to request data beyond them.

Red Flags Worth Walking Away From

Several warning signs come up consistently across FDA guidance and academic patient-safety resources: claims of "100% success" or guaranteed results; treatment offered for conditions the FDA has specifically flagged as targets of deceptive marketing, including autism, COVID-19 complications, and various neurological, cardiac, and orthopedic conditions with no approved stem cell treatment; a clinic that won't disclose its cell source or processing method; pressure to pay upfront for a treatment described as "not yet insurance-covered because it's cutting-edge" rather than because it isn't approved; and the absence of a real informed-consent document explaining specific risks. The FDA has documented serious harms from unapproved regenerative products, including blindness, infections, tumor formation, and dangerous immune reactions — real risks, not theoretical ones.

Ask About Safety, Cost, and What Happens If Something Goes Wrong

Before treatment, ask what specific adverse reactions are possible, whether the treatment requires immunosuppression or hospitalization, whether repeat treatments are typically needed, what the full cost is including any follow-up care, and what recourse exists if you're harmed. Ask, too, what alternative — including standard, insurance-covered — treatments exist for your condition, and why the clinic believes this option is preferable.

Verify Independently Before You Commit

Don't rely solely on what the clinic tells you. Search ClinicalTrials.gov directly for the treatment and confirm it's an actively registered, IRB-overseen trial if that's the claim being made. If you have concerns about a specific clinic or want to verify a treatment's status, the FDA's Office of Combination Products can be reached at ocod@fda.hhs.gov, and any adverse event after treatment should be reported through the FDA's MedWatch program. These are free, publicly available checks that take a fraction of the time — and cost — of the treatment itself.

Bottom Line

The honest, evidence-based version of this advice isn't "avoid stem cell therapy" — regulated, FDA-approved stem cell treatments and legitimate clinical trials genuinely help patients every year, and this site covers many of them. The advice is to ask pointed questions before you pay: what's the regulatory status, what exactly is being injected, what's the physician's evidence, and can you independently verify any of it. A clinic confident in its offering will welcome those questions. One that deflects them is telling you something important.
