Fig. 4. Pseudoglandular structures under the hepatic capsule express bile duct
markers in the 17.5-day knockout liver. Pseudoglandular structures under
the hepatic capsule (arrows) are reactive with fluorescent DBA (B) and
an anti-nidogen antibody (D) in the knockout liver. Hepatocytes under
the capsule react with neither DBA (A) nor the anti-nidogen antibody
(C) in the wild-type liver. Scale bars: 50 µm.
