Cover: The Islet of Hope, by Patrick C. Moore and Christopher J. Rhodes of the Kovler Diabetes Center at The University of Chicago and Mark Atkinson
of the Department of Pathology at the University of Florida. The image is of a human pancreatic islet from a patient with
long-standing type 1 diabetes from the JDRF nPOD collection (subject 6040). The red cells are somatostatin-producing δ-cells,
the orange cells are glucagon-producing α-cells, and the lone green cell is an insulin-producing β-cell. The name Islet of
Hope was chosen because after more than 20 years of type 1 diabetes, an insulin-producing β-cell is still present.
