The world’s first person cured of type 1 diabetes
The Chinese Woman Cured with Stem Cell Therapy: A Landmark in Regenerative Medicine
Introduction
In a major milestone for modern medicine, a 25-year-old woman from Tianjin, China, became the first person in the world with type 1 diabetes to achieve “functional recovery” through a revolutionary stem cell treatment. Although not a case of cancer, this success has enormous implications for oncology, as it paves the way for using stem cells in the treatment of other severe diseases, including cancer. This breakthrough marks a shift toward therapies that regenerate damaged tissues rather than simply managing symptoms.
Diagnosis and Medical Background
The patient was diagnosed with type 1 diabetes at age 14. The autoimmune disease had destroyed the insulin-producing beta cells in her pancreas. Over the years, she underwent two liver transplants and a failed pancreatic transplant. Despite intensive insulin therapy, her blood glucose remained difficult to manage, and her quality of life was severely compromised.
Treatment Start: June 2023
In June 2023, researchers from Peking University, led by Professor Deng Hongkui, initiated an experimental procedure that would radically change her prognosis. The team extracted fat cells from the patient and chemically reprogrammed them into induced pluripotent stem cells (iPSCs). These were then differentiated into pancreatic islet-like cells capable of producing insulin.
Implant Procedure
Approximately 1.5 million islet cells were implanted into her abdominal muscles in a minimally invasive 30-minute procedure. The abdominal region was selected due to its excellent vascularization and integration potential. Within just 75 days, the patient began producing insulin naturally without external assistance.
Medical Results Achieved
After nearly two and a half months, she no longer required insulin injections. Her HbA1c levels normalized, and continuous glucose monitoring revealed that 98% of the time her blood sugar remained within the optimal range. Over one year later, her condition remains stable with no need for external insulin and no significant side effects. She now enjoys the freedom to eat a regular diet, including desserts and her favorite traditional Chinese hotpot.
Implications for Oncology
Although this procedure focused on diabetes, the technology has exciting applications in oncology. Personalized cellular therapy, based on a patient’s own reprogrammed cells, could become an effective tool against cancers resistant to standard treatments.
Chinese scientists have also recently developed a radical cancer treatment by genetically modifying tumors to resemble pig tissue. This unusual resemblance triggers a powerful immune response against the tumors. In early-stage clinical trials, 90% of participants with advanced cancer experienced tumor shrinkage or halted progression. These innovations show how biotechnology may revolutionize oncology care.

Advantages of Using the Patient’s Own Cells
Using the patient’s own reprogrammed cells brings one major benefit: eliminating the risk of immune rejection. Unlike conventional transplants, this therapy theoretically does not require lifelong immunosuppressants. In this case, the patient was already on immunosuppressive medication due to previous transplants, but future trials aim to assess long-term immunological safety in broader populations.
Current Limitations and Challenges
Despite the promising results, this therapy is still in its early stages:
- The costs remain very high.
- Cell reprogramming is a complex and delicate lab procedure.
- Long-term effects are not fully understood.
- It’s unclear whether success will be consistent across all patients.
Although the case is groundbreaking, it remains isolated. Further clinical trials are underway, with two more patients undergoing the same protocol under close medical supervision.
Future Perspectives in Cellular Therapy
This case highlights two powerful directions in modern therapy:
- Personalized medicine – where each patient receives treatment tailored from their own biological material;
- Tissue regeneration – applicable in oncology, autoimmune diseases, neurological disorders, and spinal injuries.
Experts predict that within the next decade, stem cell therapies will become widely accessible. With proper regulation, infrastructure, and continued innovation, these treatments could soon be a standard tool in hospitals worldwide.
Conclusion
The story of this Chinese woman is not only a medical first — it is a symbol of what science can achieve when innovation meets persistence. The functional recovery from type 1 diabetes using reprogrammed stem cells offers real hope for those with chronic autoimmune or oncologic conditions. It may be just the beginning of a new medical era — one in which the body holds the key to its own healing.
