ONLINE COVER Moving Beyond β Testing. Dressed in the colors of the season, the stem cell–derived pancreatic β cells shown on this week's cover produce insulin and develop into human islet-like structures. In this week's Perspective, Bruin et al. discuss recent advances that have spurred new optimism for a cell-based therapy for diabetes as well as remaining challenges that hamper the translation of stem cell–derived pancreatic β cells to the clinic.
