Figure 4.
Corrosion casts provide a three-dimensional image of putative ductus venosus in Ah −/− mice. The portal vein (PV), inferior vena cava (IVC), and ductus venosus (DV) are shown in corrosion casts of wild-type (A) and congenic age-matched Ah −/− (B and C) livers. Corrosion casts are representative of at least six Ah +/+ and six Ah −/− mice. The cast in C shows the patent DV from an Ah −/− mouse after individual vessel branches were removed.
