How to Read a Stem Cell or Regenerative Medicine Quote

Clinics abroad offer injections and infusions described as stem cells, exosomes, cord blood, amniotic products or other “regenerative” treatments for conditions ranging from joint pain to neurological disease. The quotes often look like any other medical package, with a total, a list of sessions and some inclusions. Reading one well means asking about the product first and the package second.

Why these quotes are different

When you compare knee replacement quotes, nobody disputes that the operation works. You're comparing price, scope and quality. With most regenerative products, the open question is whether the treatment is approved and proven for your condition at all. A cheaper quote for an unproven treatment isn't a better deal than an expensive one. Neither has shown it delivers what's being sold.

Question 1: what exactly is the product?

Ask the clinic to state in writing:

• the type of material: cells from your own body (for example, from fat or bone marrow), donor tissue, or a product derived from birth tissue;
• whether it's processed, cultured or expanded in a lab, and which lab;
• how it will be given (injection into a joint, intravenous infusion, or another route) and how many doses;
• what, if anything, is being measured, such as cell counts, and who certifies the measurement.

The US Food and Drug Administration lists stem cells, stromal vascular fraction, umbilical cord blood, amniotic fluid, Wharton's jelly, ortho-biologics and exosomes among regenerative products that need FDA approval before they can be marketed to US consumers. It says that before approval, these products need FDA oversight in a clinical trial (FDA, current as of 2024).

Question 2: has a regulator approved it for your condition?

The FDA says the only stem cell products it has approved are blood-forming stem cells derived from umbilical cord blood, for patients with disorders that affect blood production. It lists conditions these products are not approved for, including orthopedic conditions, chronic pain, neurological disorders, autism, blindness, and heart and lung disease.

A clinic in another country works under that country's rules, not the FDA's. So ask the clinic which authority in its own country has authorized the specific product for your condition. Then ask for the authorization reference so you can check it yourself. For a Colombian clinic, ask it to name the Colombian authority and the approval document, rather than accepting a general claim that the treatment is “legal here.” The NHS treatment-abroad checklist (reviewed 2023) suggests a similar test for UK patients: is the treatment licensed by the UK medicines regulator, approved by NICE, or listed in an international clinical trials database, and have you verified the claims with independent sources?

Question 3: is this a clinical trial, or a product for sale?

Some clinics describe their treatment as a “study” or a “protocol.” If so, ask for:

• the trial registration number;
• the ethics committee that approved it;
• the written informed-consent document;
• who pays for what, and whether you pay to take part.

Be careful with listings. The FDA notes that a listing on clinicaltrials.gov, or a company's registration with the FDA, doesn't mean a product is legally marketed. It also warns that if you're charged for these products, or offered them outside a clinical trial, you're likely being deceived and offered an illegal product. That warning is written for the US market, but the logic travels: a paid treatment presented as research deserves extra scrutiny.

Question 4: what evidence does the clinic offer?

Ask for published, peer-reviewed results for your condition and the specific product, not testimonials, before-and-after videos or the number of patients treated. If the clinic offers only patient stories, write that down. It's an answer.

Now read the price lines

If the product questions have satisfactory answers, read the package the way you would any procedure quote. Typical lines to look for:

• Harvest procedure: if your own cells are used, the procedure to collect them, with any anesthesia.
• Processing: the lab fee for preparing the product.
• Administration: each injection or infusion, and any imaging used to guide it.
• Number of sessions: whether the “protocol” includes repeat doses, and what later doses cost.
• Medical assessment: who examined your records and confirmed the diagnosis.
• Follow-up: what monitoring is included, and for how long.
• Exclusions: treatment of any adverse reaction, travel and lodging.

Risks belong in the decision, not the fine print

The FDA says it has received reports of blindness, tumor formation and infections linked to unapproved regenerative products. It lists safety concerns that include life-threatening blood infections, unwanted immune reactions, cells forming the wrong tissue, and contamination during processing. It also lists the risk that people put off approved treatments that might help. That last one is easy to miss. Paying for an unproven injection instead of an established treatment has a cost that doesn't appear on any quote.

Bring the quote to a doctor at home

Before you commit, show the quote and the clinic's product information to a specialist in your home country who treats your condition. Ask them three things. What established treatments are available for you? What would they expect the regenerative product to add? And would anything in the clinic's plan affect care they might give you later? A specialist with no stake in the clinic's treatment is the best check you have on the claims in the quote.

Read the payment and refund terms closely

Regenerative treatments are often sold as multi-session protocols, sometimes paid in full up front. Before paying, find out:

• whether you can pay per session rather than for the whole protocol;
• what's refundable if a physician decides after the first session that you shouldn't continue;
• what happens to the payment if the product isn't available on the scheduled date;
• who the payee is, and whether that matches the clinic's legal name.

Full prepayment for a course of unproven treatment puts all the risk on you.

Questions to send before any deposit

1. What is the exact product, where does it come from, and which lab prepares it?
2. Which authority has approved this product for my condition, and what is the reference?
3. Is this a registered clinical trial? If so, what is the registration number and which ethics committee approved it?
4. What published, peer-reviewed results exist for this product and my condition?
5. Which physician reviewed my records, and what is their specialty?
6. What follow-up do you provide, and what happens if I have a reaction after I return home?

Ask for the answers in writing. How a clinic responds to these questions tells you as much as the answers themselves.

If you decide to go ahead

Get the product name, the lab, the dose, the administration route and the treating physician in writing before you pay. Check the physician's credentials. Our guide to verifying a doctor in Colombia before paying a deposit covers the registries. Bring a full record home for your own doctors. If you're a US patient and have a bad reaction, the FDA asks that problems be reported through its MedWatch program.

Frequently asked questions

Are stem cell treatments approved by the FDA?

The FDA says the only stem cell products it has approved are blood-forming stem cells derived from umbilical cord blood, for disorders that affect blood production. It lists orthopedic conditions, chronic pain and neurological disorders among uses that are not approved.

A clinic abroad says its treatment is legal there. What should I ask?

Ask the clinic to name the authority in its own country that approved the specific product for your condition, and to give the approval reference so you can check it. A general statement that the treatment is legal is not the same as an approval for your use.

Does a clinicaltrials.gov listing mean a treatment is approved?

No. The FDA notes that a clinicaltrials.gov listing or a company's FDA registration does not mean a product is legally marketed. If a clinic calls its treatment a study, ask for the registration number, the ethics committee approval and the consent document.

What risks has the FDA reported with unapproved regenerative products?

The FDA says it has received reports of blindness, tumor formation and infections, and lists concerns including serious blood infections, unwanted immune reactions, contamination and delays in getting approved treatments that might help.

What should a regenerative medicine quote itemize?

The harvest procedure if your own cells are used, lab processing, each injection or infusion and any imaging guidance, the number of sessions and the cost of repeats, the physician assessment, follow-up monitoring and exclusions such as treatment of adverse reactions.
