These results showed higher expression of the ‘pancreatic progenitor’ markers Pdx1, Hnf1β and Lgals419 across all our KC, KCATMΔ+ and KCATMΔΔ tumor cell lines (both from primary tumors and liver metastasis), in comparison to markers of the other subtypes (Fig. 2A and Supplementary Table 2). This evidence concerns the gene CALCA and neoplasm.
