Notch receptor expression in the adult zebrafish telencephalon.
Notch receptors are differentially expressed in the ventricular zone of the adult zebrafish telencephalon. Brightfield micrographs of cross-sections at the indicated levels through the telencephalon; the schematic at the bottom-left illustrates the corresponding areas in the cross-section shown at a higher magnification. A, B and C, expression of zebrafish notch1a, notch1b and notch3 in the rostral telencephalon, respectively; dashed line indicates the division between ventral and dorsal telencephalon; A′ -C ′, Higher magnification of the ventral expression domain; A′′ -C ′′, Higher magnification of the dorsal expression domain; dashed line indicates the dorso-lateral most region. Arrowheads and unfilled arrowheads indicate, respectively, strongly and weakly expressing cells located at the ventricular surface; arrows indicate expressing cells in the parenchyme. Abbreviations: Dll, lateral part of the dorso-lateral telencephalic area; Dil, intermediate part of the dorso-lateral telencephalic area; Dm, dorso-medial telencephalic area; dT, dorsal telencephalic area; vT, ventral telencephalic area; Vd, dorsal nucleus of the ventral telencephalon; Vv, ventral nucleus of the ventral telencephalon. Scale bars = 200μm in A (applies to B, C); 25 μm in A′ (applies to B′ ,C′ , A′′ -C′′ and A′′′ -C ′′′).
