As expected, HPAF-II xenografts showed glandular structures, typical of highly differentiated tumors, with higher FOXA1 expression, whereas PANC-1 xenografts exhibited solid and compact tumor sheets without lumens, indicative of poor differentiation, along with higher GATA2 and ABCC4 expression (Supplementary Figure S2). This evidence concerns the gene GATA2 and neoplasm.
