Figure 12From: Expression of LGR-5, MSI-1 and DCAMKL-1, putative stem cell markers, in the early phases of 1,2-dimethylhydrazine-induced rat colon carcinogenesis: correlation with nuclear β-catenin 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.
