Immunohistochemistry using sections of paraffin-embedded tissues was carried out as previously described11 (link),19 (link). Antibodies used for IGFBP7 and Latexin staining were mouse anti-human IGFBP7 (Abcam) and goat anti-Latexin (R&D) as described for flow cytometry. For IGFBP7 staining, samples were incubated in a steamer for 20 min in S1699 (Dako) prior to incubation with antibody.
Stained slides were scanned by a Mirax microscope (Zeiss, Jena, Germany) and the Panoramic Viewer software (3D Histech, Budapest, Hungary) was used to take images.
