Beyond Efficacy: How Extraction Location and Other Considerations Affect the Future of Diabetes Stem Cell Therapy

This narrative review evaluates the potential of stem cell–based therapies in curing the underlying causes of diabetes type 1 and type 2, with a focus on the accessibility, safety, and efficacy of various stem cell extraction locations compared with standard diabetes treatments. We identified studies examining various stem cell types and sources, including embryonic stem cells, bone marrow–derived hematopoietic stem cells, neural stem cells, umbilical cord–derived mesenchymal stem cells, and adipose-derived stem cells. Among these, umbilical cord and adipose stem cells appear to offer the strongest potential for treatment, with both lasting results and easy accessibility. However, barriers such as cost, feasibility, and the durability of long-term outcomes must still be considered. While stem cell therapies offer an exciting avenue for the treatment of diabetes, further research is necessary to resolve these challenges and position stem cell transplant as a viable alternative to existing therapies, including exogenous insulin and oral hypoglycemic medications.
