All images were acquired with an Olympus digital camera (Olympus U-TV1X-2 CC)<br />

using Cell^F imaging-software (Olympus Deutschland GmbH, Germany). The<br />

settings for exposure time, contrast, brightness, and pinhole were identical for each<br />

set of pictures of a figure, except when indicated otherwise in the text. To allow an<br />

improved visibility, images of some figures were adapted by linear brightness<br />

enhancement and each of the compared images of the shown figures was treated<br />

identically using Cell^F software.<br />

Quantification and comparison of fluorescence intensities<br />

To quantify fluorescence emission intensities the original acquired image data were<br />

used. Mean intensity levels (mean intensity profile, Cell^F imaging software) were<br />

calculated from indicated areas of interest, expressed as pixel grey scale values. To<br />

compare general autofluorescence of pancreatic tissue samples, mean fluorescence<br />

intensities were calculated from selected comparable image areas that display<br />

pancreatic acini as the typical histological structure, as shown for example in Fig. 2.<br />
