Tumour epithelial cells were further reclustered into two distinct subclusters (Subcluster 1 and Subcluster 2), and DUSP9 was predominantly expressed in Subcluster 1, which was enriched with other oncofetal and stemness‐related genes such as AFP, GPC3, IGF2, ANPEP and EPCAM (Figure 3J). Here, DUSP9 is linked to neoplasm.
