E9.5 WT or DKO embryos from dams administered Suff or GVAD diets were probed by ISH for Cyp26a1 (A), and β-carotene metabolizing genes: Bco1 (B) and Bco2 (C). All images are shown to the same scale. For each, only the lateral view is shown. Hindbrain (bracket) and foregut presumptive liver (arrow) structures are noted. Bco1 staining was much stronger than Bco2.
