Researchers at the University of Chicago have developed a skin graft utilizing engineered stem cells that can trigger the release of insulin and successfully regulate blood sugar levels, as well as prevent weight gain when consuming a high-fat diet. This revolutionary treatment could eliminate the pain and discomfort from current methods of monitoring and regulating blood sugar through injections. The stem cells in the graft were engineered, with the use of CRISPR, to release a hormone that mimics glucagon (called GLP-1) and trigger the pancreas to release insulin. GLP-1 is also shown to combat obesity due to its appetite suppressing properties. The engineered stem cells formed into a layer of skin tissue and were applied to the subjects. In animal models, 80% of the diabetic mice receiving the engineered skin graft exhibited the release of insulin following food consumption resulting in lower blood glucose levels and reduced body weight.
