FGFR4 and hepatocellular carcinoma: The data from FGF19 expression with FGFR4 and EpCAM expression from the 24 immunohistochemically stained HCC sections were used to determine the correlation between FGF19 and its receptor FGFR4 and between the cancer stem cell marker EpCAM, respectively, in the ST-NASH-CR- HCC sequence.
