notch and delta gene expression in zebrafish trunk neural tube. All images are of transverse sections through trunk neural tube. Images in each row are of the same section. First column: fluorescent detection of RNA hybridization using notch and delta probes. Second column: localization of post-mitotic neurons using anti-Hu antibody. Third column: composite images of RNA and Hu localization. Both Hu-positive and negative cells expressed n1a (A-C), dlA (J-L) and dlB (M-O) and dlD (Q-R) whereas predominantly Hu-negative cells appear to have expressed n1b (D-F) and n5 (G-I). Scale bar, 10 μm.
