The Ck19-CreERT and Opn-iCreERT2 drivers are highly specific towards cholangiocytes in non-injured livers. (a,b) Schematic experimental outline. Mice were injected with tamoxifen and sacrificed three days or three weeks later. The percentage of tdTomato+ Hnf-4α+ cells was quantified in liver sections of Ck19-CreER-tdTomato and Opn-CreER-tdTomato mice (n = 7–8 mice per experiment; 18 pictures per mouse). No statistically significant differences were detected between groups. (c) Immunofluorescent detection of Hnf-4α and tdTomato in Ck19-CreER-tdTomato and Opn-CreER-tdTomato mice three weeks after tamoxifen. Scale bars: 50 μm.
