Expression of these genes was validated using immunohistochemistry or immunofluorescence staining in both PDCs and respective tumor tissue (Fig. 3d and Supplementary Fig. 3c, d), and this was recapitulated on flow cytometry for AXL (HN137) and AURKB (HN159 and HN220) (Supplementary Fig. 3e, f, j, k). The gene discussed is AXL; the disease is neoplasm.
