In a major leap forward for diabetes treatment, a 36-year-old Canadian woman with type 1 diabetes is now living insulin-free, thanks to a single stem cell implant.
Amanda Smith, who had spent most of her life managing the disease with daily insulin injections and constant blood sugar monitoring, received a lab-grown stem cell treatment as part of a clinical trial.
The implanted cells, designed to function like those of a healthy pancreas, settled in her liver and began naturally controlling her blood sugar levels.
Her experience, documented in the New England Journal of Medicine, is one of ten cases out of twelve where participants were able to remain off insulin for at least a year after the procedure.
“It’s history now,” Smith said. “I feel like a normal person again.”
The breakthrough offers new hope to millions living with type 1 diabetes, a chronic autoimmune condition in which the body attacks its insulin-producing cells. However, the treatment comes with a caveat: patients must take immune-suppressing drugs to prevent their bodies from rejecting the implanted cells. These drugs carry risks of infections and other complications.
Still, researchers are optimistic. Efforts are already underway to develop next-generation stem cell therapies that won’t trigger immune responses, potentially eliminating the need for immunosuppressants.
