Stem Cell Therapy in Frankfurt | Proven Uses, Risks, Cost

"Stem cell therapy" covers treatments with very different levels of evidence.

• Established: stem cell (bone marrow) transplantation for leukaemia, lymphoma, myeloma and some other blood and immune disorders. University Hospital Frankfurt performs about 80 to 100 transplants a year.

• Approved for specific conditions: a small number of cell products, such as CAR-T cells for certain blood cancers and a limbal stem cell product for a rare eye injury.

• Available in Germany under special national approval: Obnitix (MSC-FFM), mesenchymal stromal cells developed in Frankfurt, for a serious complication after a transplant.

• Unproven: stem cell or exosome injections and infusions marketed for arthritis, Parkinson's disease, ALS, Alzheimer's disease, multiple sclerosis outside specialist transplant programmes, autism, diabetes, erectile dysfunction and anti-ageing. These are not approved medicines for these uses. The European Medicines Agency and Germany's Paul-Ehrlich-Institut have warned patients about such offers.

Costs differ widely. A stem cell transplant for leukaemia can range from €263,650.

This guide explains the types of stem cell treatment, what the evidence shows, how to check whether a treatment is approved, estimated costs and how to prepare.

Types of Stem Cell Treatment

What the Evidence Shows?

Cartilage defects in younger patients can be treated with autologous chondrocyte implantation, which uses the patient's own cartilage cells (not stem cells). This is an approved surgical treatment, quite different from stem cell injections for arthritis.

A Warning About Unproven Stem Cell Treatments

The European Medicines Agency (EMA) warned in 2020 that unregulated cell-based therapies "may not be safe or effective". It reported serious, sometimes fatal, side effects, including infections, immune reactions, tumour formation, vision loss and bleeding in the brain.

In March 2025, Germany's Paul-Ehrlich-Institut (PEI), the federal authority for these medicines, and the EMA again warned against commercial offers of unapproved cell therapies. Warning signs they list include:

• promises of healing for serious diseases without scientific evidence

• "experimental therapies" offered commercially outside approved clinical trials

• no confirmation of approval from the EMA or a national authority

• high costs that health insurance does not cover

Legal is not the same as proven. Some cell preparations can be given legally in Germany under limited national rules, for example when made under a doctor's direct responsibility. This does not mean they have been shown to work.

Germany has seen the consequences of unregulated stem cell treatment. In 2011, health authorities in North Rhine-Westphalia closed the XCell-Center, a private clinic in Düsseldorf that had injected stem cells into the brains of children, after the death of a child.

How to check a stem cell offer?

1. Ask for the name of the product and whether it is approved by the European Commission (through the EMA) or by the Paul-Ehrlich-Institut, and for which condition.

2. If it is offered as part of a clinical trial, ask for the trial registration number and check it on the EU Clinical Trials Register or the German Clinical Trials Register (DRKS). Genuine trials do not usually charge patients for the experimental treatment.

3. Ask what evidence supports the treatment for your condition, and read it with your own doctor.

4. Be cautious of clinics that treat many unrelated conditions with the same cells.

Stem Cell Transplantation in Frankfurt

What does it involve?

Time in Germany:

• autologous transplant: often about 1 to 2 months

• allogeneic transplant: often about 3 to 4 months, as early complications are most common in the first 100 days

Risks

• Infections while blood counts are low

• Mouth sores, nausea and tiredness from conditioning chemotherapy

• Graft-versus-host disease after allogeneic transplant, where donor immune cells attack the patient's tissues

• Organ damage, infertility and, rarely, graft failure

• Treatment-related death, particularly after allogeneic transplant. Your team will give you an estimate for your situation.

Hospitals and Centres in Frankfurt

When choosing a centre, check:

• whether it is a recognised transplant centre with experience in your condition

• the number of transplants it performs each year

• whether the treatment offered is an approved medicine or part of a registered trial

• access to intensive care, infectious disease specialists and donor registries

• whether it has an international patient office that provides written estimates and interpreters

The centres below are examples with verified information. This is not a ranking or endorsement.

Cost of Stem Cell Therapy in Frankfurt

Costs depend mainly on the type of treatment.

What affects the total cost?

How International Patients Can Prepare?

Medical documents to gather

• Diagnosis and pathology reports, including bone marrow reports and genetic or molecular results.

• Treatment history, with chemotherapy drugs, cycles, dates and response.

• HLA typing of the patient and any siblings, if done.

• Recent scans (on disc or download link) and blood tests.

• Heart, lung and kidney tests, and infection screening.

• For other conditions, specialist letters and imaging, and details of all previous treatments.

Reports in languages other than English or German may need translation.

Travel and administrative documents

Visa. Most non-EU patients need a visa for medical treatment. Applications usually need the hospital's invitation letter with a cost estimate, proof of funds and health insurance. Allow for the full expected stay.

Other items to arrange:

• proof of funds or an insurer's guarantee of payment

• accommodation near the hospital for the patient and a caregiver

• a caregiver, who is essential after a transplant

Questions to Ask Before Choosing Stem Cell Treatment

1. Is this treatment an approved medicine for my condition, or part of a registered clinical trial? What is its name and registration number?

2. What evidence shows it works for my condition?

3. What are the risks, including serious ones?

4. For a transplant, what type do you recommend, and what are my chances of success and treatment-related risks?

5. How many patients with my condition does your centre treat each year?

6. How long will I need to stay in Germany?

7. What does the cost estimate include and exclude?

8. Who will manage complications after I return home?

Recovery and Follow-Up

• After a transplant. Blood counts recover over weeks. Infection precautions, medicines and frequent checks continue for months. The immune system can take a year or more to recover fully, and vaccinations are repeated.

• Long-term follow-up. Regular checks for relapse, late effects and, after allogeneic transplant, chronic graft-versus-host disease. Follow-up is usually shared between the German centre and your doctors at home.

• After other cell treatments. Ask in advance how you will be monitored, who to contact about side effects, and how results will be measured.

Frequently Asked Questions

1. What conditions are treated with stem cells in Frankfurt?

Established uses are stem cell transplants for leukaemia, lymphoma, myeloma and some other blood and immune disorders. For arthritis, neurological diseases, autism, diabetes and ageing, stem cell treatments are unproven and not approved medicines.

2. Does stem cell therapy work for knee arthritis?

In a large 2023 trial, bone marrow, fat-derived and umbilical cord cell injections were no better than a steroid injection for knee pain at 12 months, and none changed cartilage on MRI.

3. Can stem cells treat Parkinson's, ALS or Alzheimer's disease?

Not yet. Research is ongoing, but there is no approved stem cell treatment for these conditions. Consider treatment only within a registered clinical trial.

4. How much does stem cell therapy cost in Frankfurt?

A stem cell transplant for leukaemia can range from €263,650.

5. Is stem cell therapy legal in Germany?

Approved cell medicines and registered trials are legal. Some unapproved preparations can also be given legally under limited national rules. Legal does not mean proven. The EMA and the Paul-Ehrlich-Institut have warned against commercial offers of unapproved cell therapies.

6. How can I check whether a stem cell treatment is approved?

Ask for the product name and whether it is approved by the European Commission or the Paul-Ehrlich-Institut for your condition. For a trial, ask for the registration number and check the EU or German trial registers.

7. What are the risks of unproven stem cell treatment?

The EMA has reported infections, immune reactions, tumour formation, vision loss and bleeding in the brain, some fatal. There are also financial costs without proven benefit.

8. How long will I need to stay in Frankfurt for a stem cell transplant?

Often about 1 to 2 months for an autologous transplant and about 3 to 4 months for an allogeneic transplant.

9. Is exosome therapy the same as stem cell therapy?

No. Exosomes are small particles released by cells. No exosome product is approved in the EU.

10. Is stem cell therapy covered by insurance?

Stem cell transplants for established indications are covered by German insurance for residents. International patients usually pay themselves unless their insurer agrees in advance. Unproven stem cell treatments are not covered.
