Dynamics of the tracer in vivo.
(a) Fluorescence signal detected over time after injection of 1 μg of Cy5.5-exendin-3. (b) xfOCM (virtual structural section and maximum projection of vascularization) with fluorescence images at different time points indicated with a star symbol in a. Depth is color-coded in micrometers. Stripes in the vascularization images are due to residual pancreas movements. Scale bar: 200 μm.
