In comparison with the cell type-specific signatures identified in hepatoblastoma related clusters65, we found that cluster 2 in ABC-Myc tumors is most likely the ‘HB associated Promyelocyte’, while clusters 3, 9 and 12 are most likely the ‘HB associated Erythroid’ (Fig. 4b, d), although these three clusters have different enrichment of biological functions (Supplementary Data 2). Here, MYC is linked to hepatoblastoma.
