Fig. 6From: Pre-Microporation Improves Outcome of Pancreatic Islet Labelling for Optical and 19F MR ImagingConfocal microscopy of the fixed sliced pancreatic islet samples. Upper row – a control sample of unlabelled pancreatic islets; middle row – islets labelled by microporation according to the modified protocol at 600 V; lower row – islets labelled by endocytosis. Artificial colours represent autoluminescence (green), DAPI (blue) and the fluorescent signal of ICG bound to nanoparticles (red). The far right column shows an overlap of green, blue and red signals. The scale bar represents 50 μmBack to article page
