ABSTRACT
Several vertebrate genes of the Hairy/Enhancer-of-split (HES) family are involved in paraxial mesoderm segmentation and intersomitic boundary establishment/maintenance. Here, we show that the zebrafish hairy-related gene, her6, highly homologous to the mammalian and chicken HES-1 genes, is expressed in the posterior part of each segmented somite and in stripes in the anterior presomitic mesoderm (PSM), and also in a dynamic, segmentally restricted pattern during hindbrain segmentation, with all rhombomeres expressing her6 at different time points and at different levels.
