Representative mouse bioluminescence images.

<p>Panels A and B are ventral and dorsal bioluminescence images of a representative control mouse on days 0, 4 and 8 after the start of the experiment. Panels C and D are ventral and dorsal bioluminescence images of a representative mouse on days 0, 2, 4, 6 and 8 after treatment of STZ. Images were standardized to a light intensity scale on the right. The daily mouse blood glucose level and the liver ROI luminescent intensity were recorded under each image.
