This Section seeks to understand how regenerative and developmental biology can be applied to repair or replace tissues that are damaged by diabetes, ranging from the pancreatic beta cell to tissues that are subject to complications. This focus extends to understanding how diabetes and the aging process influence the development and function of organs and tissues. Several laboratories focus on studying beta cells, their initial developmental specification, how they can be regenerated, and how they might be replaced through stem-cell or induced-pluripotent (iPS) cell technologies. Other researchers study the functions of differentiated islet cells, with a particular focus on understanding mechanisms governing beta cell proliferation and survival. Another major interest is the aging process, how it affects stem cells and developed tissues, and how it can be slowed to promote healthy aging and prevent chronic disease. Finally, investigators study basic principles of stem cell pluripotency and cell development of importance in diabetes.
