From: Abcg2a is the functional homolog of human ABCG2 expressed at the zebrafish blood–brain barrier
Abcg2a and Abcb4 protein localize to claudin-5 positive vasculature. Sagittal section of an adult zebrafish brain stained with hematoxylin and eosin (H&E) and probed with anti-Abcg2a, C219 (cross-reacts with Abcb4), and claudin-5 antibodies. Descending row panels show the entire brain (upper), section of the brain (middle) and an enlarged region (lower). Antibody staining is pseudo colored in gray, and DAPI in blue. Scale bar upper = 250 μm, middle = 100 μm, lower = 50 μm
