Pré - inscription individuelle obligatoire. Introduction: Zebrafish (Danio rerio) is an ideal model organism for the study of vertebrate development. The ability of zebrafish to produce thousand of embryos in a synchronous manner has made zebrafish an invaluable tool for genetic and chemical screens. Prof. Rod W. Wilson (Biosciences, University of Exeter) Water chemistry varies greatly across zebrafish culture facilities, with no guidelines or even basic advice available on many parameters important for healthy populations. Zebrafish is recognized as an ideal model organism for investigating the cellular and molecular mechanisms underlying heart formation and regeneration. The ability of zebrafish to generate many embryos every time they breed makes them especially useful for high throughput drug screening. When using animals in research, it is important to minimise animal suffering by using the least sentient organism possible to answer the question at hand. Zebrafish are highly prolific with a single female capable of spawning several hundred eggs every week. It is easy to produce mutations in zebrafish, and screening programmes have been developed to find mutations that affect particular biological systems, such as the development of the nervous system. This teleost was first described in the 1800s as an inhabitant of the Ganges River in India. As toxicologists and regulators begin to recognize that there are many parallels between zebrafish and other vertebrate organisms, the use of zebrafish in both human and ecological toxicity assessments will become more common. Fu… By using zebrafish embryos as a model, we have demonstrated that Hematopoietic Stem Cells (HSCs) emerge directly from the aorta floor through a process called the Endothelial Haematopoietic Transition (EHT). Read more about zebrafish research in these blog posts. This animal is popular among aquatic hobbyists, and ‘GloFish’ are the first approved genetically modified pet for commercial use.

NERYXCOM / Shutterstock. Zebrafish are increasingly being used as a model system for understanding the genetic and neuronal basis of behavior. The fish gets its name for its similarity to the zebra by having a few horizontal stripes on each side of the body. Zebrafish have become a popular model for both human and ecological toxicity assessments. This development is catalyzed by a unique combination of strengths, including the ability to isolate mutants, make transgenic animals with different cell types labeled by fluorescent markers, and record from neurons in the networks with conventional electrophysiological techniques; most importantly, transparent zebrafish larvae allow the imaging of neuronal structure and function in the living animal. Finally, zebrafish are amenable to in vivo imaging modalities, genetic and environmental manipulations, electrophysiological recordings, and neurobehavioral studies, potentially allowing key mechanistic insights to be gained rapidly by traditional hypothesis-driven experiments. They grow at an extremely fast rate, developing as much in a day as a human embryo develops in one month. With the aid of pharmacological agents, zebrafish can remain transparent well after larval retina function is established, making them an ideal model for visual studies. Native to South Asia, it is a popular aquarium fish, frequently sold under the trade name zebra danio (and thus often called a "tropical fish" although both tropical and subtropical). Despite these limitations, the advancement of genome editing technologies and their application in zebrafish have provided an avenue to effectively study the causal link between mutant gene variants and various cardiovascular diseases, especially CHD. In addition, many genes implicated in human neurological disorders have highly conserved orthologues in the zebrafish genome, suggesting that the biochemical events underlying pathogenesis could be recapitulated in the zebrafish nervous system. Zebrafish embryos are nearly transparent which allows researchers to easily examine the development of internal structures. Zebrafish produce hundreds of offspring at weekly intervals providing scientists with an ample supply of embryos to study. Zebrafish Models in Neurobehavioral Research emphasizes the growing importance of zebrafish in neurobehavioral research and portrays an extensive, thorough perspective on the emergence of zebrafish as robust and translational models.
