Platelets are abundant in common human tumours but not in healthy tissues. Formalin fixed sections from primary human adenocarcimonas and healthy human tissues underwent immunofluorescence for platelets (red) and nuclei (blue) with an anti-CD41 antibody and counterstained with Hoechst® nucleic acid stain. Representative 60x magnification confocal fluorescence microscopy images demonstrating the presence of platelets within primary human breast (n=3), bowel (n=3) and lung (n=3) adenocarcinomas (A-C). Representative 60x magnification confocal fluorescence microscopy images of healthy breast (n=2), bowel (n=2) and lung (n=2) tissues displaying no CD41 staining (D-F).
