On the cover: Purified human pancreatic islets for transplantation in type 1 diabetes. Immunohistochemistry of isolated human islets derived from a deceased donor depicting insulin-producing β-cells in red and glucagon-producing α-cells in green. These isolated human islets were generated according to the Clinical Islet Transplantation Consortium standard operating procedure used for phase 3 recipients with type 1 diabetes whose long-term metabolic outcomes are reported in the article by Flatt et al., “β-Cell Secretory Capacity Predicts Metabolic Outcomes Over 6 Years After Human Islet Transplantation,” in this issue of Diabetes (p. 749).
