Expression pattern of Notch signal components in the optic tectum of adult zebrafish. Expression patterns of notch1b, notch3, and deltaA (dla) in transverse sections of the adult zebrafish optic tectum. Hoechst is for nuclear staining. Magnified views of the PGZ, indicated in the dorsomedial area of the PGZ. A-C, A′-C′: notch1b was strongly expressed in the medial margin and weakly expressed in deep layer of the PGZ. E-G, E′-G′: notch3 were expressed in the ventral margin and deep layer of the PGZ. I-K, I′-K′: and dla were expressed in the medial margin of the PGZ. Scale bar = 200 µm (A-K), 25 µm (A′-K′). CCe, corpus cerebelli; PGZ, periventricular gray zone; TeO, tectum opticum.
