Although additional research is required to establish their efficacy and safety, stem cells have the potential to be used as a diabetes therapy alternative.The replacement or regeneration of pancreatic beta cells, which are in charge of manufacturing insulin, is one potential application of stem cells in the treatment of diabetes. In those with type 1 diabetes, the immune system kills these cells, which prevents the body from producing insulin. Theoretically, stem cells may produce new beta cells and increase insulin output.
