Same method at every depth. What changes is how long we stay with it.
“Stem cells” is four different things.
They are not variations on one treatment. The law treats them as separate categories, and the difference decides whether what you are being offered needs a lab certificate or a drug licence.
Your own cells, barely altered
Taken from your fat or bone marrow, concentrated, and returned in the same procedure for the same job they already did.
Treated as a medical procedure rather than as a drug, provided the cells are minimally manipulated and used for what they normally do.
Your own cells, grown in a lab
The same starting cells, cultured over weeks to multiply them before they are given back.
Growing them in culture is not minimal manipulation, so the exemption stops applying. That makes it a drug, which means registration.
Donor cells from umbilical cord
Mesenchymal cells from a donated cord or placenta, grown in a lab and given to someone else. This is what almost every Bangkok clinic actually sells.
A drug under Thai law, requiring registration on the back of clinical trials. No mesenchymal stem cell product is registered with the Thai FDA.
Exosomes
Not cells at all, the packets cells release. Sold alongside stem cells and often described as if they were the same product.
A different product in a different class again. A clinic that uses one word for both is not being careless.
What is actually permitted here.
This is the part no clinic page in Bangkok prints, and it is the part that decides everything else.
Two disease areas rather than a menu
The Medical Council recognises stem cell therapy as standard treatment in two places. The first is blood disease and blood cancer, a closed list of eight conditions including thalassaemia, marrow failure and some treatment-resistant autoimmune disease, performed by a transplant haematologist. The second is disease of the cornea and ocular surface. Everything else needs case-by-case Council approval or an approved research protocol. That is essentially every indication advertised to healthy adults in this city.
Since 28 May 2026, these are drugs
A Ministry of Public Health notification under the Drug Act made products containing cells or tissue of living organisms medicines. There is an exemption, and it is narrow: the cells must be minimally manipulated AND used for the job they already did. Growing them in culture fails the first half, so the standard Bangkok offer is a drug, and no mesenchymal stem cell product is registered with the Thai FDA.
A licence to operate is not a licence to inject
A physician's licence, a clinic licence, a GMP lab and a consent form are four real things, and not one of them is an approval for the product itself. The most careful pages in this city now say so: they set out the registration rule accurately, and then never say whether their own product meets it. A rule quoted next to a price is not compliance with it.
“Investigational” and an invoice do not go together
In September 2026 the Medical Council's cell therapy subcommittee and the Royal College of Orthopaedic Surgeons said stem cell treatment for knee osteoarthritis is not approved standard of care, that around twenty projects remain in research, and that a provider running research may not charge patients for it. The pooled trial evidence points the same way. A page that calls its own treatment investigational and then publishes a price per knee has answered its own question.
The advertising itself is regulated
Medical facility advertising here requires prior approval, and false or exaggerated claims carry a fine and up to a year's imprisonment: with the Drug Act stacking a second penalty on top for anything that is now a medicine. Thai courts have handed custodial sentences to a doctor, a clinic owner and their advertising agency over false medical advertising. The health ministry's own list of banned advertising words names stem cells specifically. This is enforced rather than theoretical.
Summarised from the Medical Council of Thailand’s published position, Ministry of Public Health announcements under the Drug Act, and the Medical Facility Act. It is a summary, not legal advice. Parts of this framework are still being tested. If you are making a decision on it, take your own advice.
The eight conditions, and the one other area.
This is what the Medical Council recognises as standard treatment. If your condition is not here, what you are being offered is research: which needs an approved protocol, two ethics approvals, and a clinician who tells you so.
Blood disease and blood cancer
- Blood cancers
- Bone marrow failure: myelodysplastic syndrome, aplastic anaemia
- Thalassaemia
- Inherited metabolic disorders
- Inborn errors of immunity
- Treatment-resistant autoimmune disease: lupus, multiple sclerosis, systemic sclerosis
- Solid cancers in children
- Steroid-resistant graft-versus-host disease
Performed by a haematologist with transplant credentials, in a transplant setting. Anything outside this list goes to the Council’s subcommittee case by case, it is not available on request.
The eye
Disease of the cornea and the ocular surface, using limbal stem cells. The second and only other area recognised as standard treatment.
Not on either list
Knees and joints. Anti-ageing and longevity. Autism, Parkinson’s, cerebral palsy. Skin, hair, fertility, fatigue. Liver, kidney and heart disease. Every one of these is advertised in Bangkok, and none is approved treatment.

Checked against the primary Thai instruments listed above. This is a summary for patients rather than legal advice, and parts of this framework are under challenge. If you are making a decision on it, take your own advice.
Six questions, and what a good answer sounds like.
Ask these anywhere, including here. A clinic that answers all six specifically is worth listening to. One that does not has told you what you need to know.
The better pages now state the rule correctly: cells grown in culture must be made to GMP standard and registered with the Thai FDA.
Stating the rule is not the same as meeting it, and none of them says their own product does. No mesenchymal stem cell product is registered with the Thai FDA. Ask for the registration number rather than the rule.
Conditions treated run from knees to autism to ageing.
The Medical Council's approved list is eight blood conditions plus disease of the eye surface. Ask which of those yours is, and if it is none of them, ask to see the approved research protocol.
Trial results and percentages are quoted freely.
Every figure belongs to somebody else's study. Ask how many patients they have treated, and what happened to them.
Improvement is promised in weeks to months.
Almost nobody records a baseline or re-measures the thing they claim to change. Ask what gets measured before, and when it is measured again.
Nearly everyone is presented as a candidate.
Almost no page publishes who should not have this. Ask what would rule you out, and watch whether the answer is specific.
Safety is described as excellent, sometimes as perfect.
Serious harm is documented. Three patients lost most of their sight after injections at one clinic, and the published safety record for injecting culture-expanded cells into a joint runs to a few hundred procedures. Ask for the risks in writing, and for what happens if something goes wrong.[2][3]
We do not sell this. Here is why, and what we do instead.
We do not offer stem cell therapy
Not for joints, not for immunity, not for ageing. The science is interesting; that is not the reason. It has not been shown to work for these things in people, and Thai law does not permit it outside blood and eye disease. Both of those would have to change before the answer does.
We will read what you have been offered
Bring the quote, the consent form and the certificate of analysis. A physician will tell you what the product actually is, which class it sits in, and what the evidence for your indication looks like. That costs you a consultation and no more.
If you go ahead anyway, get a baseline
Most people who have this done never find out whether it worked, because nothing was measured before. If you are going to do it, measure first and measure again after on the same instruments. We will run those panels whether or not the treatment is ours, and it is the only way you will ever know.
What we do instead, for the same problems
For a painful knee: loading, strength, weight, and a physiotherapist who assesses it. For inflammation and fatigue: a panel that finds the cause. For ageing: the boring, proven things, measured every quarter. Less exciting, considerably better evidenced, and a fraction of the price.
The questions people actually arrive with.
Including the ones a clinic selling this would rather you did not ask.
