Immunofluorescence localization of antigen specific cells and proliferating cells. a faint green serotonin positive cells without counter stain, b tryptophan hydroxylase positive faint green cells, c chromogranin A positive cells identified in saffron color, d lysozyme positive cells, faint green, and (e) Andy fluor green fluorescent EdU labeled proliferating cells show as fluorescent green nuclei. The nuclei were stained blue with DAPI except in (e) where they were stained with propidium iodide showing orange-red color. Images are magnified to 200X, bar = 40 μm
