Understanding Stem Cell Transplant
Stem cell transplantation is a broad term that encompasses several distinct medical procedures, the most established of which is hematopoietic stem cell transplantation. HSCT involves replacing the body's blood-forming stem cells, which reside primarily in the bone marrow, with healthy stem cells to restore the production of normal blood cells. This procedure, also historically known as bone marrow transplant, is a proven and potentially curative treatment for many blood cancers including leukemia, lymphoma, and multiple myeloma, as well as non-malignant conditions such as aplastic anemia, sickle cell disease, thalassemia, and severe combined immunodeficiency. The field has advanced enormously over the past several decades, with improvements in conditioning regimens, donor matching, graft-versus-host disease prevention, and supportive care leading to progressively better outcomes and broader applicability.
Beyond traditional hematopoietic transplantation, the broader field of stem cell therapy encompasses a range of regenerative medicine approaches that use different types of stem cells to repair or replace damaged tissues and organs. Mesenchymal stem cells derived from bone marrow, adipose tissue, or umbilical cord tissue are being investigated for conditions including osteoarthritis, spinal cord injury, heart failure, autoimmune diseases, and neurodegenerative disorders. While some of these applications have shown promising results in clinical trials, many remain experimental and have not yet achieved the level of evidence required for routine clinical use. Patients considering stem cell therapy abroad must carefully distinguish between established, evidence-based treatments and unproven therapies that may be marketed aggressively but lack sufficient scientific support.
The cost of stem cell transplantation in the United States is prohibitively expensive for many patients, with autologous HSCT costing $350,000 to $500,000 and allogeneic HSCT reaching $500,000 to $800,000. These costs include pre-transplant chemotherapy conditioning, the transplant procedure itself, extended hospitalization in protective isolation, blood product support, antimicrobial therapy, graft-versus-host disease management, and months of intensive follow-up. International centers in Turkey, India, South Korea, and other countries offer the same proven procedures at 50 to 90 percent lower cost, performed by experienced hematologists and transplant physicians at accredited facilities. Centers like Acıbadem Maslak Hospital maintain HEPA-filtered transplant units, stem cell processing laboratories, and comprehensive supportive care capabilities that match leading Western centers.
Proven Indications for Stem Cell Transplant
Hematopoietic stem cell transplantation has well-established indications supported by decades of clinical evidence and international consensus guidelines. For blood cancers, autologous HSCT is a standard treatment for relapsed or refractory Hodgkin and non-Hodgkin lymphoma, multiple myeloma as part of initial treatment, and selected cases of germ cell tumors. Allogeneic HSCT is the treatment of choice for many patients with acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndromes, chronic myeloid leukemia that has failed targeted therapy, and severe aplastic anemia. The decision between autologous and allogeneic transplant depends on the specific disease, its stage and risk classification, the availability of a suitable donor, and the patient's overall health and fitness.
Non-malignant conditions that are treated with HSCT include severe aplastic anemia, which responds well to allogeneic transplant from a matched sibling donor; sickle cell disease, where transplant can provide a definitive cure by replacing the patient's defective hemoglobin-producing cells; thalassemia major, which requires lifelong blood transfusions unless cured by transplant; and severe combined immunodeficiency, a life-threatening inherited immune disorder where transplant is life-saving. Autoimmune conditions including severe multiple sclerosis, systemic sclerosis, and Crohn's disease are increasingly being treated with autologous HSCT after intensive immunosuppression, with growing evidence supporting its effectiveness in carefully selected patients who have failed conventional therapy.
At centers like Acıbadem Maslak Hospital and Memorial Şişli Hospital, the hematology and transplant teams evaluate each patient individually to determine whether HSCT is appropriate, what type of transplant is recommended, and what the expected outcomes and risks are. These centers follow international guidelines including those from the European Society for Blood and Marrow Transplantation and the American Society for Transplantation and Cellular Therapy, ensuring that patients receive evidence-based treatment recommendations. The transplant teams include experienced hematologists, transplant physicians, specialized nurses, pharmacists, and supportive care specialists who together provide comprehensive care throughout the transplant journey.
- Acute myeloid leukemia — allogeneic HSCT for intermediate and high-risk disease
- Acute lymphoblastic leukemia — allogeneic HSCT for high-risk or relapsed disease
- Multiple myeloma — autologous HSCT as part of standard front-line treatment
- Hodgkin and non-Hodgkin lymphoma — autologous HSCT for relapsed/refractory disease
- Severe aplastic anemia — allogeneic HSCT, particularly from matched sibling

Emerging Stem Cell Therapies
The field of stem cell therapy is evolving rapidly, with numerous emerging applications in various stages of clinical development. CAR-T cell therapy, which involves genetically engineering a patient's own T cells to target and destroy cancer cells, has achieved remarkable results in certain blood cancers and is now approved for specific indications including relapsed B-cell acute lymphoblastic leukemia and certain types of lymphoma. While not technically a traditional stem cell transplant, CAR-T therapy uses sophisticated cellular engineering approaches that have emerged from the stem cell transplant field and is increasingly being offered at leading international transplant centers as an alternative or complement to conventional HSCT.
Mesenchymal stem cell therapy is being investigated for a wide range of conditions including osteoarthritis, degenerative disc disease, heart failure, liver cirrhosis, and neurological conditions. While early clinical trials have shown promising results in some areas, particularly in orthopedic applications and graft-versus-host disease treatment, the evidence base for most mesenchymal stem cell applications remains limited, and regulatory approval for these therapies varies significantly between countries. Patients considering these emerging therapies should exercise caution and seek treatment only at reputable centers that conduct their programs within proper clinical trial frameworks or under appropriate regulatory oversight.
It is crucial for patients to distinguish between established, evidence-based stem cell treatments and unproven therapies that are marketed commercially without adequate scientific support. The International Society for Stem Cell Research has published guidelines warning patients about clinics that offer unproven stem cell treatments for conditions where the scientific evidence is insufficient. Red flags include clinics that claim stem cells can treat a wide variety of unrelated conditions, charge high fees for treatments not covered by insurance or regulatory approval, do not provide informed consent about the experimental nature of the treatment, lack proper clinical trial registration, and do not publish their outcomes in peer-reviewed journals. Reputable centers like Acıbadem Maslak Hospital are transparent about which stem cell treatments are established standard of care and which remain investigational.
Safety & Ethical Considerations
Safety in stem cell transplantation depends on multiple factors including the quality of the transplant center, the expertise of the medical team, the appropriateness of the treatment for the patient's condition, and the quality of supportive care. For established hematopoietic stem cell transplantation, the key safety metrics to evaluate include the center's annual transplant volume, treatment-related mortality rates, infection rates, GVHD incidence and management outcomes, and long-term survival data. Centers should be willing to provide this information to prospective patients and should have outcome data that are comparable to international benchmarks. Accreditation by JACIE (Joint Accreditation Committee of ISCT and EBMT) or FACT (Foundation for the Accreditation of Cellular Therapy) specifically certifies transplant programs that meet rigorous quality standards.
For emerging stem cell therapies, safety considerations are even more critical because the long-term effects of many of these treatments are not yet fully understood. Patients should ensure that any investigational treatment is being conducted within a properly designed clinical trial with institutional review board approval, informed consent, adverse event monitoring, and follow-up protocols. The International Society for Cellular Therapy and the ISSCR have published guidelines for responsible clinical translation of stem cell research that provide a framework for evaluating the safety and legitimacy of emerging therapies. At accredited centers, all investigational treatments are conducted within appropriate regulatory frameworks with full transparency about the experimental nature of the therapy and the potential risks involved.
My autologous stem cell transplant for multiple myeloma at the hospital in Istanbul saved my life and saved us over $300,000 compared to treatment in the US. The hematology team was outstanding, and the transplant unit was world-class. I am now in complete remission.

Frequently Asked Questions
Frequently Asked Questions
What is the difference between stem cell transplant and bone marrow transplant?
They are essentially the same procedure. 'Bone marrow transplant' is the older term that refers to the original method of collecting stem cells from the bone marrow. Modern techniques often collect stem cells from the blood (peripheral blood stem cell transplant), but the procedure is functionally identical. The terms are used interchangeably.
How long does recovery from stem cell transplant take?
Engraftment occurs 10-21 days after transplant. Initial hospital stay is 3-6 weeks. Most patients need 3-6 months of restricted activity and close monitoring. Full immune recovery takes 12-24 months for allogeneic transplants. Autologous transplant recovery is generally faster.
Can stem cells cure autoimmune diseases?
Autologous HSCT is showing promising results for severe autoimmune conditions including multiple sclerosis and systemic sclerosis. It is not a guaranteed cure, but studies show significant long-term remission rates in carefully selected patients. This approach is available at specialized centers.
Is CAR-T cell therapy available abroad?
Yes, CAR-T therapy is increasingly available at leading international centers, though access varies by country and specific product. Some Turkish and Indian centers are developing CAR-T programs. Costs abroad range from $100,000-$200,000 compared to $373,000-$475,000 in the US per approved product.
How do I avoid stem cell therapy scams?
Beware of clinics that claim to treat a wide variety of unrelated conditions, charge high upfront fees, lack proper accreditation, refuse to share outcome data, or pressure you to decide quickly. Stick to accredited hospitals with published transplant programs and seek second opinions from established hematologists.
