Story summary

Researchers implanted CRISPR-edited pancreas cells in a type 1 diabetes patient, enabling insulin production without immune suppression.
Led by Sana Biotechnology, the study offers hope for a long-term cure for the autoimmune disease.
Preliminary results are promising but involve only one patient and low cell doses, leaving efficacy unproven.
Vertex Pharmaceuticals reports ten out of twelve participants no longer need insulin after a year.
Experts are cautiously optimistic, with further studies scheduled for 2026.
