Double immunofluorescent staining of CD133 with VEGFR-2 and CD34 in NPC tissues. (a) The immunofluorescence expression of CD133 (green) and VEGFR-2 (red). (b) The immunofluorescence expression of CD34 (green) and CD133 (red). Nuclei were counterstained by DAPI (blue) in the merged pictures. Arrows and arrowheads indicate the double positive cells and the enlarged (insets). Original magnification is 400x (a) and 200x (b). Scale bar represents 50 μm.
