Clinical Application of Umbilical Cord Mesenchymal Stem Cells Preserves ß-cells in Type 1 Diabetes.

ABSTRACT

Type 1 diabetes (T1D) is a chronic autoimmune disease associated with complications that reduce the quality of life of affected individuals and their families. The therapeutic options for T1D are limited to insulin therapy and islet transplantation; these options are not focused on preserving ß-cell function and endogenous insulin. Despite the promising outcomes observed in current clinical trials involving allogeneic Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) infusion for the management of T1D, the precise underlying mechanism of action remains to be elucidated. In this correspondence, we propose prospective mechanisms of action of WJ-MSCs that may be mediating their observed capability to preserve ß-cell function and prevent T1D progression and provide recommendations for further investigations in clinical settings. We also highlight the efficacy of WJ-MSCs for therapeutic applications in comparison to other adult MSCs. Finally, we recommend the participation of muti-centers governed by international organizations to implement guidelines for the safe practice of cell therapy and patients' welfare.
