No evidence of YFP co-expression with the hepatic stellate marker desmin in murine models of biliary injury. Representative merged images of liver sections from mice (A) 8 weeks post-BDL, (B) after 3 weeks of CCl4 treatment, and (C) after 3 weeks of DDC treatment. Note the distinct staining of long, thin cells in the sinusoids. Green = YFP (Cy5), red = desmin (Cy3), blue = DAPI. * = representative bile ducts; v = portal vein. Scale bar = 20 μm.
