Summary The rich phenotypic diversity that characterizes the vertebrate skeleton results from evolutionary changes in regulation of genes that drive development. Although relatively little is known about the genes that underlie the skeletal variation among fish species, significant knowledge of...
Summary This review addresses the use of comparative studies of development to help understand the mechanisms underlying the evolution of morphological and physiological diversity. Mutation analysis in experimental model organisms is at the core of our understanding of how development works, and...
Summary Tetrapod vertebrae are sclerotome‐derived metameric structures. Cells from this tissue provide cartilage that surrounds the notochord and give rise to the vertebral centrum as well as the vertebral arches. Eventually, later on, the cartilage is remodeled into bone. Vertebral body...
Summary Although fish species represent probably about half of all vertebrate species, the structure and material properties of fish skeletons are poorly understood. Since osteocytes (cells within the bone tissue) are believed to orchestrate the modeling and remodeling responses in mammalian...
Summary We investigated the tooth pattern on the lower jaw of adult farmed Atlantic salmon (Salmo salar L.) to elucidate whether this pattern is more regular, with less variations, than that observed in wild Atlantic salmon studied previously. A highly regular and predictable tooth pattern, in...
Summary We have developed a protocol for simultaneous detection of BrdU and PCNA on paraffin sections of teleost tissues and have tested it successfully on dental and orofacial tissues of Atlantic salmon (Salmo salar) and zebrafish (Danio rerio). By combining decalcification of the tissue,...
