The National Guideline for Cell Therapy and Regenerative Medicine
A comprehensive framework balancing cutting-edge medical innovation with ethical principles and patient safety
Explore the FrameworkImagine a future where a damaged heart can be repaired, a failing liver regenerated, or Parkinson's disease reversed—not with synthetic drugs or invasive surgeries, but by harnessing the body's own innate power to heal itself.
This is the promise of regenerative medicine, a field that stands at the forefront of a medical revolution. Across the globe, scientists are learning to direct the processes of cell renewal and tissue repair. Yet, this rapid progress brings complex questions: How can such powerful technologies be developed safely? Who has access to these treatments? What are the ethical boundaries?
In 2018, Iran took a decisive step to answer these questions by formally launching "The National Guideline for the Establishment and Operation of Cell Therapy and Regenerative Medicine Departments." This document, announced by the Minister of Health on November 19, 2018, serves as a comprehensive national blueprint 1 .
It was designed with a dual mission: to pave the way for cutting-edge cell-based therapies for patients with conditions that do not respond to conventional treatments, and to establish strict oversight of cell therapy centers to protect patients and stop unauthorized abuses 1 . This guideline represents Iran's commitment to becoming a regional leader in a transformative medical field, ensuring that progress is made responsibly and ethically.
The translation of stem cell research from laboratory benches to patient bedsides has been rapid. While the science advanced quickly, the clinical applications often lagged, creating a gap between discovery and safe, effective treatment.
To bridge this gap, Iran's Ministry of Health and Medical Education (MOHME) established the Cellular Medicine and Infertility Department (CMID) under its Curative Affairs Deputy 1 .
This department was tasked with a critical mission: to provide independent guidance and decisions for Cell Therapy & Regenerative Medicine (CTRM) services across the country.
The national guideline provides the structural basis for how CTRM services should operate in public and private therapeutic centers. Its oversight is designed to be strict, ensuring uniformity in quality and safety 1 .
Parallel to this operational guideline, Iran also developed a sophisticated ethical framework. In 2020, the Iranian National Committee for Ethics in Biomedical Research approved a comprehensive update to the nation's ethical guidelines for stem cell and regenerative medicine research 6 .
Authorizes use of human embryos up to 14 days old, but only when surplus from IVF procedures and obtained legally. Prohibits transplantation into human embryos/fetuses and creation of human-animal chimeras 6 .
Therapeutic cloning (somatic cell nuclear transfer) is permitted but limited to 14-day embryo development. Reproductive cloning of humans is unequivocally prohibited 6 .
Genetic manipulation of surplus IVF embryos for research is allowed (14-day rule), but in vivo manipulation of human fetus is forbidden. Enhancement or eugenics purposes are banned 6 .
To understand how Iran's regulatory environment enables real-world medical advances, one can look to the field of regenerative urology. For over three decades, researchers at the Pediatric Urology and Regenerative Medicine Research Center in Tehran have been pioneering techniques to rebuild and restore damaged urological tissues and organs 5 .
Their work provides a perfect case study of the "bench to bedside" journey that Iran's national guidelines are designed to support.
A key challenge in urology is repairing a severely damaged urethra, the tube that carries urine out of the body. Traditional grafts often fail due to poor integration and scarring. The Iranian team developed an innovative solution using decellularization and recellularization 5 .
A segment of tissue is taken from an animal donor. All original cellular material is completely washed away, leaving a pure extracellular matrix (ECM) scaffold 5 .
The acellular scaffold is "seeded" with a patient's own cells (autologous cells), which can include stem cells or other progenitor cells 5 .
The newly created, living graft is surgically implanted. The scaffold provides structure for the patient's cells to form new, functional tissue 5 .
This approach has shown significant success in preclinical models. In animal studies (e.g., rabbits), the recellularized grafts demonstrated excellent structural integration with the host tissue. The grafts were successfully revascularized (new blood vessels grew in) and showed evidence of functional recovery, such as restoring continence in anal sphincter reconstruction models 5 .
The scientific importance is profound. By using a patient's own cells, the risk of immune rejection is minimized. The decellularized scaffold acts as an instructive template, guiding tissue regeneration in a way that synthetic materials cannot. This experiment underscores a major shift in medicine: from simply replacing damaged organs to actively engineering the body to regenerate itself.
| Item | Function | Example in Iranian Context |
|---|---|---|
| Decellularized Extracellular Matrix (dECM) | Provides a natural, 3D biological scaffold that supports cell attachment and growth without provoking a strong immune response. | Used in creating grafts for urethral, bladder, and anal sphincter reconstruction 5 . |
| Mesenchymal Stem Cells (MSCs) | Versatile "master cells" that can differentiate into bone, cartilage, muscle, and fat cells; also secrete factors that reduce inflammation and aid healing. | Sourced from bone marrow, adipose tissue, or umbilical cord blood; used in orthopedic and cardiac repair studies 3 9 . |
| Induced Pluripotent Stem Cells (iPSCs) | Adult cells (e.g., skin cells) reprogrammed to an embryonic-like state, capable of becoming almost any cell type; avoids ethical issues of embryonic stem cells. | Used to create patient-specific models for disease and develop personalized cardiac treatments 3 6 . |
| Growth Factors | Signaling proteins (e.g., VEGF, FGF) that stimulate cellular processes like proliferation, differentiation, and new blood vessel formation (angiogenesis). | Incorporated into tissue-engineered scaffolds to accelerate and direct the healing process 8 . |
| Biocompatible Polymers | Synthetic or natural materials (e.g., chitosan, specific polyesters) used to create custom-designed scaffolds for tissue support. | Companies like ChitoTech and Tissue Regeneration Corporation in Iran manufacture such biomaterials for clinical use 8 . |
The national guidelines have helped foster a vibrant and growing research and commercial landscape. A recent review identified 56 Iranian companies active in the field of tissue engineering, including 29 commercial enterprises, 17 service providers, and 10 research institutions 8 . The majority are based in Tehran, with a notable surge in formations after 2004 8 .
This data reveals a strategic pivot. While the current market offerings are dominated by biomaterials (scaffolds, etc.), the research focus of these companies is sharply shifting toward cell-based therapies.
This indicates a maturing industry that is building on its foundational strengths to pursue more complex and transformative regenerative products for the future.
Pioneering work at the Pediatric Urology and Regenerative Medicine Research Center in Tehran has developed techniques to rebuild and restore damaged urological tissues and organs using decellularization and recellularization approaches 5 .
Iranian researchers are conducting clinical trials using stem cell therapy for Parkinson's disease, showing promise in alleviating symptoms like tremors and rigidity 7 .
Several preclinical and early clinical studies have demonstrated that mesenchymal stem cells can reduce infarct size and improve heart function after a heart attack 3 .
The Royan Institute and Royan Stem Cell Technology company are internationally recognized for their work in stem cell therapy for skin and cartilage disorders 8 .
Iran's establishment of a national guideline for cell therapy and regenerative medicine is more than a bureaucratic milestone; it is a declaration of its ambition to be a responsible innovator in one of the most promising fields of modern science. By combining clear operational rules with deeply considered ethical principles, Iran has created a framework that seeks to balance rapid scientific advancement with unwavering patient safety and moral integrity.
The progress is tangible—from specialized research centers and a growing number of biotech companies to promising clinical trials for debilitating diseases. While challenges such as funding limitations and the need for larger-scale clinical trials remain, the foundation is solid 3 .
As one analysis concluded, Iran's investment in scientific infrastructure and progressive policies has positioned it as a leading country in stem cell science in the Muslim world 3 . The future of healing is being written today, and with its national guideline as a compass, Iran is helping to steer the world toward a future where the body's own power to heal can be safely and ethically unlocked for all.
