This comprehensive volume discusses in vitro laboratory development of insulin-producing cells. It encompasses multiple aspects of islet biology—from embryonic development and stem cell differentiation to clinical studies in islet transplantation, regulation of islet beta-cell regeneration, pancreatic progenitors, mathematical modelling of islet development, epigenetic regulation, and much more. The chapter authors represent leading laboratories from around the world who contribute their international perspectives and global expertise. Collectively, they provide the reader with a concise yet detailed knowledge of processes and current developments in islet regenerative biology. Pancreatic Islet Biology, part of the Stem Cell Biology and Regenerative Medicine series, is essential reading for researchers and clinicians in stem cells or endocrinology, especially those focusing on diabetes.
