Figure 2From: Expression of growth factor receptors and targeting of EGFR in cholangiocarcinoma cell lines RT-PCR for housekeeping genes and growth factor receptors. A) PCR analysis to ensue the presence and integrity of five housekeeping genes from TFK-1, representative for all cell lines used. B) mRNA expression of growth factor receptors in four CC cell lines (n. d. = not detected).Back to article page
