CD276 and hepatoblastoma: Further examination of hepatoblastoma tumor cell line markers uncovered bimodal expression of CD326, KRT19, LIN28B and CD276 dividing cell lines into two phenocopies: cholangiocyte-precursor-like (KRT19highCD326high) and hepatoblast/hepatocyte-precursor-like (KRT19lowCD326intermediate; Figure 8C), akin to the normal ontogeny (1, 41).
