Quick answer
Stem cell therapy in Mexico usually means injections of mesenchymal stem cells, often from umbilical cord Wharton's jelly. They act mainly by releasing signals that modulate inflammation and support repair. Clinical trials show favorable results in some areas, such as knee osteoarthritis and skin quality, and no benefit in others, such as autism, ALS and heart failure. These therapies are not FDA-approved for these uses; in Mexico they are regulated by COFEPRIS. Choose a clinic that reviews your records first, shows product licences and batch certificates, and tells you honestly when a therapy won't help.
Stem cell therapy in Mexico has become a common search for people in the United States who have read about regenerative medicine and want options closer to home than Asia or Europe. It is also a field with many exaggerated promises. This guide explains, with published evidence, what these therapies are, where they may help, where they don't, and how to evaluate a clinic.
What is stem cell therapy?
Most clinics in Mexico use mesenchymal stem cells (MSCs). At Longevity Clinic they come from Wharton's jelly, the tissue of the umbilical cord, donated after healthy births and processed by a licensed laboratory.
Their main effect is not turning into new tissue. MSCs act mostly by releasing signals, such as growth factors and molecules that modulate inflammation, help form new blood vessels and protect damaged cells. This is called the paracrine effect (Gnecchi, 2016). Part of those signals travel inside exosomes, tiny vesicles cells use to communicate (Kalluri and LeBleu, Science, 2020).
What does the evidence show?
| Area | What clinical studies found |
|---|---|
| Knee osteoarthritis | A 2026 meta-analysis of 28 randomized trials found less pain and better function than control injections, without clear cartilage regrowth on MRI. Read the summary. |
| Skin quality | A 2026 meta-analysis of 39 studies found wrinkles reduced by about 20% on average with exosome-based therapies. Read the summary. |
| Hair thinning | A 2024 meta-analysis linked stem cell-derived products to greater hair density and thickness. Read the summary. |
| Diabetic foot ulcers | A 2025 meta-analysis of 6 trials found more complete wound closure with MSCs. Read the summary. |
| Autism | A Duke University trial with 180 children found no improvement in social skills versus placebo. |
| ALS | A phase 3 trial did not meet its primary goal. |
| Crohn's perianal fistulas | A second phase 3 trial with 568 patients found no difference versus placebo, contradicting the first. |
The pattern is clear: some indications have favorable trials, others have negative ones, and many have only small studies. A trustworthy clinic tells you which group your condition belongs to.
Is it regulated?
In Mexico, cell products are regulated by COFEPRIS (Mexico's federal health regulator, similar to the FDA). The laboratory Longevity Clinic works with, Stem Biotech S.A. de C.V., holds two COFEPRIS sanitary licences: 24-TR-25-006-0001 (collection centre) and 24-TR-25-006-0002 (stem cell bank).
In the United States, the FDA has not approved these therapies for orthopedic, aesthetic or most other uses, and it warns consumers about unapproved products. Be wary of any clinic that says otherwise. Read more in is stem cell therapy in Mexico safe?
How it works at Longevity Clinic
- Send your records by WhatsApp or email: lab work, imaging, photos and medications.
- Free review and protocol. Dr. Joan Chávez reviews your case and designs your personalized regenerative protocol at no cost. If a therapy is not a good fit, we tell you before you travel.
- One trip. You fly to Veracruz (United flies nonstop from Houston) for an application of about 45 minutes. Your advisor helps with the hotel and offers transfer options.
- Remote follow-up by WhatsApp or video call.

What we don't treat
We do not offer cell therapies for neurological diseases (Alzheimer's, Parkinson's, autism, ALS, multiple sclerosis) or cancer. The evidence does not support it, and offering it would mean selling hope instead of medicine.
How to choose a clinic in Mexico
Before you book anywhere, ask who reviews your case, which laboratory makes the product, whether you can see the licence and the batch certificate, what the evidence is for your condition and what the total cost includes. We wrote a full checklist in questions to ask before stem cell therapy and a comparison in how to choose a stem cell clinic in Mexico.
Frequently asked questions
Is stem cell therapy legal in Mexico?
Cell products in Mexico are regulated by COFEPRIS, the federal health regulator. Laboratories that collect and bank stem cells need a sanitary licence. Longevity Clinic uses products from Stem Biotech, which holds COFEPRIS licences 24-TR-25-006-0001 and 24-TR-25-006-0002. Legal in Mexico does not mean FDA-approved: these therapies are not approved by the FDA for these uses.
Are the stem cells from my own body?
No. Longevity Clinic uses allogeneic mesenchymal stem cells from umbilical cord Wharton's jelly, donated after healthy births and processed in a licensed laboratory. That avoids a fat or bone marrow harvest from you. Each batch comes with a certificate of analysis.
Can stem cells cure my condition?
We don't use the word cure. In some conditions, such as knee osteoarthritis, trials show less pain and better function on average; in others, large trials found no benefit. Your physician will tell you which applies to you before you travel.
How long does the treatment take?
The application itself takes about 45 minutes. The review of your records and the design of your protocol happen before you travel, and follow-up is remote.
