How to Choose a Stem Cell Clinic: 10 Questions to Ask Before You Pay

Stem cell therapy should be administered by a licensed physician — ideally one with training in regenerative medicine, orthopedics, neurology, or a specialty relevant to your condition. Ask for the physician's name, medical license number, and board certifications. You can verify US physician licenses through your state medical board's website. Be cautious of clinics that are vague about who will actually perform or oversee your treatment.

There are two main sources: autologous (your own cells, typically from bone marrow or fat tissue) and allogeneic (donor cells, typically from umbilical cord or placenta). Both have legitimate applications, but the source affects cost, protocol, and regulatory status. Ask specifically: Are the cells minimally manipulated or lab-expanded? In the US, lab-expanded allogeneic cells require FDA approval unless administered under an Investigational New Drug (IND) application.

In the United States, stem cell therapies must comply with FDA guidelines. Autologous, minimally manipulated cells are generally permitted under enforcement discretion. Lab-expanded or allogeneic cells require an IND or must be administered under an approved clinical trial. International clinics operate under their own country's regulations — Mexico under COFEPRIS, Panama under the Ministry of Health, etc. Ask the clinic directly: 'What is the regulatory basis for this treatment?' A legitimate clinic will have a clear answer.

Ask the clinic to point you to peer-reviewed research supporting their protocol for your specific condition. Legitimate clinics will reference clinical trials, published case series, or at minimum explain that the treatment is experimental and why they believe it may help. Be skeptical of clinics that cite only testimonials or proprietary 'studies' that have not been published in indexed medical journals. You can search PubMed (pubmed.ncbi.nlm.nih.gov) yourself using your condition name + 'stem cell therapy.'

Stem cell therapy pricing is notoriously opaque. A quoted price may or may not include the initial consultation, lab work, imaging, the cell preparation, the infusion or injection procedure, follow-up appointments, and any medications. Ask for a written itemized breakdown before committing. Also ask: What happens if you need a second treatment? Is there a package price? Are travel and accommodation costs factored in for international clinics?

A confident, ethical clinic will offer to connect you with former patients who have consented to speak with prospective patients. This is one of the most valuable due diligence steps you can take. Patient testimonials on a clinic's own website are not a substitute — look for independent reviews on Google, Trustpilot, or platforms like StemConnect where reviews are submitted by patients, not curated by the clinic.

Stem cell therapy is not a one-time event. Reputable clinics have a structured follow-up protocol — typically including check-ins at 1 month, 3 months, and 6 months post-treatment to assess response and adjust care. Ask specifically: Who will you contact if you have a concern after returning home? Is there a physician available for follow-up questions? For international clinics, ask how they coordinate with your local physician.

Any physician who tells you stem cell therapy has no risks is not being honest with you. Known risks include infection at the injection site, immune reactions (particularly with allogeneic cells), and in rare cases, more serious adverse events. A trustworthy clinic will walk you through the informed consent process thoroughly, explain the specific risks for your protocol, and not minimize them. If a clinic dismisses your questions about risks, that is a serious red flag.

Clinics that participate in registered clinical trials (searchable at clinicaltrials.gov) or systematically track and publish patient outcomes are demonstrating a commitment to evidence-based practice. This is not a requirement — many legitimate clinics operate outside of formal trials — but it is a positive signal. Ask: 'Do you track patient outcomes? Do you publish your results?' Even informal outcome tracking suggests the clinic is paying attention to whether their treatments are working.

Look for accreditations from recognized bodies: Joint Commission International (JCI) for international clinics, state medical board licensing for US clinics, AABB accreditation for facilities handling blood and cellular products, and ISO certifications for laboratory quality. Membership in professional organizations like the International Society for Cell & Gene Therapy (ISCT) or the American Academy of Regenerative Medicine (AARM) is also a positive signal. Verify accreditations directly with the issuing organization — do not rely solely on the clinic's own claims.
