Bio/Research
Diabetes mellitus results from dysfunction, damage or loss or of pancreatic Я-cells. These cells reside in small endocrine clusters, called the islets of Langerhans, which are interspersed throughout the pancreas and secrete the hormones insulin and glucagon in response to changes in blood glucose. In order to ameliorate and eventually cure both forms of diabetes, Я-cells will need to be functionally restored, regenerated, or replaced. Pancreas and islet transplantation have demonstrated the promise of Я-cell replacement, but a short supply of transplantable tissue limits the applicability of these approaches in broadly curing diabetes mellitus. Our group is interested in understanding the mechanisms that regulate the formation of islet Я-cells from pancreatic stem or progenitor cells during solid organ formation. We focus on the gene regulatory networks at play in the progenitor cells and how these networks change during differentiation to mature endocrine cells and in the long-term maintenance of the Я-cell. We believe that a greater understanding of these genetic mechanisms and pathways will refine cell-based approaches for preventing and reversing the Я-cell deterioration and loss that occurs with diabetes.
