From: Abcg2a is the functional homolog of human ABCG2 expressed at the zebrafish blood–brain barrier
abcg2a is the only ABCG2 homolog detected in adult zebrafish brain vasculature. Paraffin-embedded adult zebrafish sections were stained with hematoxylin and eosin (H&E) probed with RNAscope probes (yellow) to detect abcg2a, abcg2b, abcg2c or abcg2d RNA, and DAPI (blue). Each punctate dot signal represents amplification of a single target RNA molecule. Sections shown are representative cross sections of the telencephalon and myelencephalon. Scale bar = 20 μm
