Porto-caval shunting and patent DV in Ahrfxneo hypomorphs mimic the Ahr-null liver vascular phenotype. Time-lapsed radiographs of the liver vascular system after injection of contrast agent into the portal vein of wild-type (A–C), Ahr–/– (D–F), Ahrfxneo/fxneo (G–I), and Arntfxneo/fxneo (J–L) mice. Arrows indicate key anatomical features of the liver: PV, portal vein; shIVC, suprahepatic inferior vena cava; BV, branching vessels.
