Representative example of a co-localization experiment between nuclear β-catenin and MSI-1 in histological colonic sections. Panel A: normal mucosa showing one MSI-1 positive cell at the base of the crypt but no nuclear β-catenin. Panel B: tumour in which many cells show nuclear β-catenin, but none express MSI-1. Original magnification 400x.
