Are Stem Cells Legal in the US?

Short answer: Partly. Only certain stem cell therapies, like those for blood disorders, are FDA-approved and legal. Most treatments haven't yet passed the necessary approval process.

FDA's role in stem cell regulation

The Food and Drug Administration (FDA) regulates the safety and effectiveness of medical treatments, including regenerative medicine. These treatments must undergo clinical trials and receive FDA approval to be legal. This ensures they meet safety and efficacy standards before being offered to the general public.

What are the FDA-approved stem cell therapies?

As of December 2024, only 3 stem cell therapies have received full FDA approval:

• Ryoncil - the first mesenchymal stromal cell therapy approved December 18, 2024 for treating steroid-refractory acute graft-versus-host disease in pediatric patients
• Lyfgenia for sickle cell disease - showing 88% complete resolution of vaso-occlusive events between 6–18 months post-treatment
• Hematopoietic stem cell transplantation (HSCT) - using stem cells from umbilical cord blood to treat certain cancers and blood disorders like leukemia

Despite limited FDA approvals, there's significant hope on the horizon. 115 global clinical trials involving 83 distinct pluripotent stem cell-derived products are currently active as of December 2024, targeting conditions in ophthalmology, neurology, and oncology. Additionally, over 5,000 registered clinical trials in the US are gathering proof of the therapy's safety and effectiveness.

Limitations of stem cell therapy in the US

Despite FDA regulations, almost 3,000 clinics in the US offer unproven therapies for a wide range of medical conditions, while Bookimed partners with verified clinics meeting strict safety standardsї. These unregulated clinics try to bypass FDA regulations by:

• Labeling treatments as "experimental". Some clinics market their treatments as part of ongoing research. However, it may lack proper oversight or adherence to safety protocols.
• Using patient-funded trials. Some clinics offer treatments through so-called clinical trials where patients pay for the therapy, blurring the line between research and commercial services.
• Operating under state-level laws. Some clinics take advantage of less stringent state regulations, allowing them to offer treatments that wouldn't pass under federal FDA guidelines.
• Offering reduced dosages. Some clinics use reduced dosages of stem cells to circumvent FDA regulations, claiming their treatments are not technically "stem cell products."

While these methods enable clinics to offer unapproved treatments, choosing one of these clinics may come with real risks:

• Safety concerns. A key issue with unapproved therapies is the lack of quality control. Without FDA oversight, there is no guarantee that the stem cells are being correctly handled and processed. Some clinics may use stem cells from unproven sources, which could be less effective or even harmful.
• Ineffective dosages. Some clinics lower the amount of stem cells used in treatments to avoid FDA oversight. However, research shows that higher dosages often produce better results. Reduced doses may not be effective enough to repair or regenerate damaged tissue properly.

Stem cell research and clinical trials in the US

The lack of FDA approval for many treatments doesn't mean they're not considered effective by U.S. scientists. In fact, numerous FDA-approved clinical trials have shown that these therapies are safe and effective in multiple application areas, such as orthopedic, neurological, and heart conditions.

However, FDA approval is required to ensure that treatments in the US undergo rigorous testing before being marketed. This ensures that the therapies meet safety standards, are properly regulated, and provide reliable outcomes for patients.

Where Is Stem Cell Therapy Legal?

Regenerative medicine is gaining traction worldwide, but the legal landscape varies significantly from one country to another. While the US has strict regulations, some nations have embraced these treatments more fully. Here's a quick overview of the most prominent destinations for legal stem cell treatment:

North and South America

Mexico

Mexico's regulatory framework for these therapies is more flexible than in the US. It allows clinics to offer treatments that are still in clinical trials elsewhere. The Federal Commission for Protection against Sanitary Risks (COFEPRIS) allows treatments in regenerative medicine, including orthopedic and neurological conditions.

However, obtaining a COFEPRIS license for this therapy takes work. The clinic must provide extensive documentation to prove its safety and compliance with regulations regarding the facility, equipment, procedures, and medical staff training.

To conduct the therapy, clinics need to obtain specific licenses, such as:

• Stem Cell Collection License (for harvesting mesenchymal stem cells);
• Surgery Room License (for performing procedures);
• Regenerative Medicine License (to legally offer treatments).

These licenses ensure clinics meet strict standards for safety, equipment, and medical expertise.

Leading COFEPRIS-approved clinics include Juventa Regenerative Medicine (5.0/5, Playa del Carmen), Giostar Stem Cell Therapy (5.0/5, Cancún), and Immunotherapy Regenerative Medicine (5.0/5, Puerto Vallarta) - all verified through Bookimed's quality assessment.

Mexico's reputation for excellence is reflected in patient experiences. One patient from the United States who received treatment at Juventa Regenerative Medicine shared: "Dr. Isabella Bernaschina was very interested in truly helping me. She was very efficient and she has considerable experience in the use of stem cells for many different conditions. She followed up after treatment to see how I was feeling and seemed to sincerely care about how I felt after treatment." (Bookimed verified review)

Colombia

Colombia's National Institute of Food and Drug Monitoring (INVIMA) governs the regulation of these therapies. Several laws and decrees ensure that stem cell collection, storage, and clinical use meet high safety and ethical standards. Before conducting any treatment, clinics should rigorously test stem cells for diseases and disease agents.

Middle East

Turkey

Regenerative medicine in Turkey is regulated by the Turkish Ministry of Health. Additionally, the Turkish Academy of Sciences and TÜBA Stem Cell Work Group support research in the country. The group also organizes conferences, symposiums, and research projects to foster collaboration between national and international scientists.

Turkey's leading Ministry of Health licensed clinics include Memorial Şişli Hospital (4.7/5, Istanbul) and Liv Hospital Ulus (4.5/5, Istanbul) - verified through Bookimed's comprehensive clinic assessment.

Turkey's reputation for excellence is reflected in patient experiences. One patient from Germany who received treatment at Liv Hospital Ulus shared: "Professor Erdal Karaöz demonstrates top professional competence, experience, versatility, seriousness and integrity. The clinic can keep up with the best in the world. A great treatment, I will repeat this in December with my wife." (Bookimed verified review)

Protecting Yourself: Ethical and Safety Considerations for Patients

Regenerative medicine is still a developing field, so it's essential to be extra cautious and well-informed. Here are some critical points to keep in mind when considering treatment:

1. Consider ethical implications

Not all types of stem cells are viewed the same in terms of ethics. One of the most debated areas is the use of stem cells from human embryos, typically left over from in vitro fertilization (IVF) treatments. Since obtaining these cells destroys the embryo, this raises ethical concerns.

On the other hand, some argue that since these embryos would otherwise be discarded, using them for medical purposes serves the greater good. You need to decide where you stand on this issue and be aware of what stem cells your treatment will involve.

2. Consult a licensed medical professional first

Always consult a licensed and qualified doctor before considering any treatment. If you're unsure where to start, Bookimed can connect you with reputable specialists and clinics worldwide for a free consultation.

3. Understand the regulations in the chosen country

Various countries have different regulations surrounding these therapies. Make sure the country you're considering has a strong regulatory framework in place to protect patients and ensure treatments are scientifically validated. The International Society for Stem Cell Research (ISSCR) 2021 guidelines require substantial evidence of effectiveness in appropriately powered, well-controlled clinical trials with statistically significant findings before stem cell products can be marketed.

4. Ensure scientific validation

Make sure the therapy for your condition is backed by peer-reviewed research and has been validated in clinical trials. You can check clinical trial data on platforms like ClinicalTrials.gov or search for published research on sites like PubMed. These platforms provide data on ongoing and completed research.

5. Beware of misleading claims

Be cautious of clinics promising miracle cures or claiming treatments for unapproved uses. These therapies are still experimental treatments for many conditions, so verify whether the therapy is part of a legitimate clinical trial or simply unproven.

6. Understand potential complications

Although clinical trials indicate the relative safety of these treatments, there can still be side effects depending on the type of stem cells and the treated condition. Ask your doctor about the short- and long-term risks of the specific treatment you are considering.

7. Don't rush your decision—consider all alternatives

Take your time to evaluate whether this therapy is the best course of action for you. Be cautious of any pressure to make quick decisions or commit to immediate treatment without exploring other options.

How to Choose a Reliable and Safe Stem Cell Clinic

With various clinics and treatments available worldwide, here are key steps to help you make informed decisions about your health:

1. Research the clinic's credentials and certifications for stem cell therapy

Ensure that the clinic complies with regulatory standards in the country, such as those set by the FDA in the U.S. or equivalent organizations elsewhere. Accredited clinics provide scientifically backed, safe treatments.

2. Verify safety protocols

Make sure the clinic follows strict safety protocols for handling, processing, and administering stem cells. Compliance with guidelines reduces risks such as contamination or infections.

3. Read reviews and patient testimonials

Investigate reviews from past patients and ask the clinic's representatives for success stories. A clinic with a solid reputation will have a history of positive patient experiences that can provide you with a clearer picture of its reliability.

4. Check for informed consent procedures

A reputable healthcare provider will fully inform you about the risks, benefits, and alternative treatments before undergoing therapy. You should never feel rushed into a decision. Avoid clinics that skim over the risks or pressure you to sign paperwork without proper consultation.

5. Ask about post-treatment monitoring and follow-up care

Ethical providers will offer ongoing care after the procedure to monitor for potential side effects or complications. This reflects a commitment to patient well-being beyond just the treatment itself.

6. Look for transparency in pricing and treatment plans

Reliable clinics are upfront about the costs involved. They should offer clear, detailed treatment plans after evaluating your case. There should be no hidden fees or surprise charges after you begin treatment.

7. Avoid clinics that promise miraculous results

Be cautious of language that promises complete recovery or miracle cures without scientific evidence. Reputable providers set realistic expectations and make it clear that results may vary.
