The number of clinics offering stem cell therapy has grown rapidly. So has the variation in quality. Some operate under rigorous medical oversight with certified cell sourcing and transparent clinical standards. Others make broad claims with little supporting evidence and minimal physician involvement.
For a patient navigating this landscape, the challenge is not finding a clinic. It is knowing how to evaluate one.
These seven questions cut through the marketing and focus on what actually matters — the safety, credibility, and honesty of the provider you are considering.
1. Where do the stem cells come from — and how are they prepared?
This is the most important question to ask. Not all stem cells are equivalent. The source, preparation method, and quality controls applied before clinical use vary significantly between providers.
Cells prepared in a GMP-certified (Good Manufacturing Practice) laboratory follow internationally recognised standards for quality, consistency, and sterility. Each batch should carry a Certificate of Analysis — a document confirming cell identity, viability, and sterility testing for that specific lot.
Umbilical cord–derived mesenchymal stem cells (UC-MSCs) sourced from Wharton’s jelly offer particular practical advantages: they are collected ethically at birth, biologically younger than adult-derived cells, and available as standardised allogeneic batches rather than varying patient to patient.
If a clinic cannot tell you where their cells come from, who certified the laboratory, or whether a Certificate of Analysis exists — that is a significant concern.
2. Which physician is overseeing your treatment — and what are their credentials?
Stem cell therapy is a medical procedure. It should be planned, overseen, and delivered by a qualified physician with relevant specialist training — not by a general wellness practitioner or non-clinical staff.
Ask specifically: which doctor will be responsible for your care? What is their specialty and how many years have they been practising? Do they have experience in the specific condition you are seeking treatment for?
In orthopaedic and neurological applications particularly, the clinical judgement of the treating physician — in determining candidacy, dosing, and delivery method — directly affects both safety and the likelihood of a meaningful outcome.
3. How will the cells be delivered — and is imaging guidance used?
The route of delivery matters. For knee osteoarthritis, the appropriate method is intra-articular injection — directly into the joint space. For neurological conditions, intrathecal or intravenous delivery may be indicated depending on the condition and protocol. A clinic applying the same delivery method to every patient regardless of diagnosis should prompt questions.
Ultrasound guidance during injection improves accuracy — ensuring cells are placed precisely where they are intended to go. Ask whether imaging guidance is used as standard, or only on request.
4. What does the clinic claim — and how do those claims match the evidence?
This question is one of the most revealing. Listen carefully to how a clinic describes outcomes.
Responsible providers use measured language: “clinical studies suggest,” “some patients experience,” “this is an emerging area of research.” They distinguish between early-phase safety data and confirmed efficacy. They acknowledge what the evidence does not yet show.
Providers who use words like “cure,” “guaranteed results,” or “proven to reverse” without regulatory backing are making claims the science does not support. The same applies to clinics that describe their technology as “revolutionary” or position themselves as the only provider capable of delivering results.
Conservative language is not a weakness. It is a sign that a clinic is operating honestly within what the evidence actually allows.
5. Will you receive a proper medical assessment before any treatment is agreed?
A credible clinic does not offer stem cell therapy to every enquiry. It assesses each patient individually — reviewing diagnosis, imaging, treatment history, current medications, and overall health — before determining whether treatment is appropriate and what protocol to recommend.
Be cautious of any provider that moves quickly from first contact to treatment recommendation without a thorough clinical evaluation. Patient selection matters. Not everyone is a suitable candidate, and a clinic that does not acknowledge this is not operating with adequate medical rigour.
6. What are the realistic risks and side effects?
Every medical procedure carries risk. A trustworthy provider discusses this openly — not to discourage, but because informed consent is a fundamental requirement of ethical clinical practice.
For UC-MSC therapy, published trials report a generally mild side effect profile: temporary soreness at the injection site, occasional fatigue in the days following treatment. Serious adverse events have been rare. But individual risk factors vary, and a full medical evaluation is required to assess them properly.
If a clinic describes a procedure as having no risks or side effects, treat that claim with scepticism. It is not consistent with how any medical intervention is responsibly described.
7. What follow-up care is provided after treatment?
Stem cell therapy is not a single event. The weeks and months following the procedure are when biological effects develop — and when any concerns should be monitored and addressed.
Ask what follow-up appointments are included. How will your progress be assessed? What should you do if you experience unexpected symptoms? Is there a clear point of contact for post-treatment questions?
A clinic that provides no structured follow-up after the procedure is not offering a complete standard of care.
Applying these questions in practice
These questions are not designed to make the process difficult. They are designed to help you identify providers who operate with genuine medical rigour — and to avoid those who do not.
Clinics operating at hospital-grade standards — such as EDNA Wellness in Bangkok — typically offer GMP-certified cell sourcing with a Certificate of Analysis per batch, specialist physician oversight, ultrasound-guided delivery, and transparent communication about evidence levels and individual suitability. These are not exceptional features. They are the baseline any responsible provider should meet.
When you ask these questions, pay attention not just to the answers but to how a clinic responds to being asked. Providers confident in their standards welcome scrutiny. Those who deflect or dismiss detailed questions are telling you something important.

Frequently asked questions
Is stem cell therapy regulated in Thailand?
Thailand has a regulatory framework for stem cell therapy administered through the Food and Drug Administration (FDA Thailand) and the Medical Council of Thailand. Clinics operating within this framework are required to meet defined standards for cell preparation and clinical practice. Patients should confirm that any provider they consider is operating in compliance with current Thai regulations and is willing to discuss this openly.
What is a GMP-certified laboratory?
GMP stands for Good Manufacturing Practice — an internationally recognised set of standards governing the production, testing, and quality control of medical-grade biological products. A GMP-certified laboratory has been independently assessed and approved to prepare cells to these standards. This certification is a meaningful marker of quality and consistency in cell preparation.
What is a Certificate of Analysis — and should I ask to see it?
A Certificate of Analysis (COA) is a document issued for a specific batch of cells, confirming that it has been tested for identity, viability, sterility, and the absence of contaminants. Yes — you can ask to see it, and a reputable clinic should be able to provide it. Its presence confirms that the cells used in your treatment have been independently verified before use.
How do I know if I am a suitable candidate?
Suitability depends on your diagnosis, disease severity, overall health, current medications, and treatment history. This can only be determined through a proper clinical assessment — not through an online enquiry form or a brief phone call. Be wary of any clinic that offers a treatment recommendation before conducting a thorough evaluation.
Should I get a second opinion before proceeding?
Yes. A reputable provider will not discourage this. Seeking an opinion from your own specialist or GP before committing to any stem cell treatment is a reasonable and responsible step. It also gives you an opportunity to discuss how this intervention fits alongside your existing care.
