Micrograph showing a longitudinal section of intestinal villi and Peyer’s patches from the jejunum of activation-induced cytidine deiminase-green fluorescent protein (AID-GFP) mice. A close-up view of the germinal centre reveals AID localization is mostly cytoplasmic. Cells were stained with DAPI (blue) and F-actin was labelled with phalloidin (red). The image was prepared by Susan Lim and collected by Kristien Zaal using a Leica SP5 confocal microscope.
