Sorting and secreting insulin by expiration date

Caption

Researchers took this image of an insulin-secreting cell from a mouse using a technique to label insulin granules, by age. In younger granules, the marker emits a green fluorescent light; as granules get older, the marker begins to emit a red fluorescence. The researchers found that cells' preference for releasing younger granules is disrupted in diabetes.
