Figure 1 Expression of TGF-β1 and TGF-β receptor II in intrahepatic cholangiocarcinoma cell lines. Immunofluorescence showed staining of TGF-β1 (A) and TGF-β receptor II (B) in HuCCT1 cells. Scale bar = 20 μm. C: Detection of TGF-β1 in supernatant of HuCCT1 by ELISA. TGF-β1 levels in the supernatant of HuCCT1 showed a time-dependent increase; D: The other ICC cell lines were incubated for 48 h and assayed by ELISA to determine the levels of TGF-β1 in the supernatants. MEC and HuH-28 cells also secreted TGF-β1 into the supernatants.
