The zebrafish, Danio rerio (formerly Brachydanio rerio), is a small freshwater fish (<4 cm in standard body length from snout to the origin of the tail fin) native to South Asia including India, Bangladesh, Pakistan, Nepal and Myanmar, where it inhabits various waters, preferably shallow and still ponds, slow-moving streams, and even rice fields (Parichy, 2015; Spence et al., 2008). Portugal. The Zebrafish Information Network (ZFIN) is the database of genetic and genomic data for the zebrafish (Danio rerio) as a model organism.ZFIN provides a wide array of expertly curated, organized and cross-referenced zebrafish research data. Unmarked tracking of shoaling . Female zebrafish spawn every 2-3 days and produce several hundred eggs in each clutch. In contrast to mammals, zebrafish are significantly cheaper and have a number of practical advantages. Zebrafish have become a popular model for both human and ecological toxicity assessments. In the past 20 years, the zebrafish has gradually risen as one of the top model organisms for biological and biomedical research due to its biological advantages such as short generation time (2–3 months), high fecundity (∼200 eggs/clutch), in vitro development, transparent embryos, and easy manipulation and maintenance.

Since the 1960s, the zebrafish (Danio rerio) has become increasingly important to scientific research. The fish gets its name for its similarity to the zebra by having a few horizontal stripes on each side of the body. Plenty of common pathogens can be examined using zebrafish model: Streptococcus iniae, Vibrio anguillarum or Listeria monocytogenes. It also covers the federal mandates that regulate the use of zebrafish in research, the need for an occupational health and safety program, and the potential hazards that come with handling zebrafish. Zebrafish is well known to be highly prolific. Experimental evidence has shown that periods of behavioral quiescence in zebrafish larvae and adults are sleep-like states, as these rest bouts are regulated by the circadian cycle, are associated with decreases in arousal, and are increased following rest deprivation. The fish also develop rapidly, and researchers can simply add drugs to … Zebrafish are increasingly being used as a model system for understanding the genetic and neuronal basis of behavior. All orders will be processed in the order received. How zebrafish mend the spinal cords: If nerve tracts in the animals are damaged, certain connective tissue cells, called fibroblasts (green), migrate to the wound and form scar tissue. The importance of Zebrafish in biomedical research Acta Med Port. It takes three months for a zebrafish to become a mature adult. LAZEN beautifully illustrated this, with nearly 100 participants from all over the continent where most attendants were researchers with beginner or intermediate experience. Since its emergence as an important model organism the molecular tools for studying zebrafish have been limited. "The zebrafish is a … Danio rerio commonly known as the Zebrafish is a tropical fish belonging to the minnow family (Cyprinidae), commonly kept in aquaria and used for scientific research. Over the past decade, zebrafish have been gaining increasing attention in behavioral neuroscience due to a number of advantages over several vertebrate and invertebrate models. Researchers presented the findings virtually today at the 2021 Society for Neuroscience Global Connectome.This zebrafish model might help scientists explore the biology … It also covers the federal mandates that regulate the use of zebrafish in research, the need for an occupational health and safety program, and the potential hazards that come with handling zebrafish. These creatures have more in common with humans than one might suspect. Thank you for registering to attend 'Zebrafish in research; a public lecture', we will be in touch with further details in due course. The facility serves as an important focal point for the education of other laboratories, students and visiting scientists. The zebrafish shares basic nervous system organization with other vertebrates; many neural circuits and cell types relevant to human disease are conserved in the zebrafish central nervous system. The use of zebrafish allows us to use a less sentient animal in research. Meet the zebrafish. The zebrafish is a small tropical fish that has become one of the favoured animal model systems for research in many areas including embryonic development, genetic analyses of disease, neural circuit function and behaviour. In recent years, zebrafish models of human pathologies to study inflammasome function in vivo have started to emerge. The Zebrafish in Biomedical Research: Biology, Husbandry, Diseases, and Research Applications is a comprehensive work that fulfills a critical need for a thorough compilation of information on this species. Water chemistry and zebrafish physiology, welfare and research reproducibility . Zebrafish develop ex utero and are free swimming with highly sensitive and accurate visual function already at 5 days postfertilization (dpf). Inflammasomes are cytosolic multiprotein complexes that regulate inflammatory responses to danger stimuli and infection, and their dysregulation is associated with an increasing number of autoinflammatory diseases. The ability of zebrafish to produce thousand of embryos in a synchronous manner has made zebrafish an invaluable tool for genetic and chemical screens. Research Focus Project leaders Members Publications Gallery Press and PR Zum Vergrößern klicken. Zebrafish have been a favorite of geneticists and developmental biologists over the past several decades due to their rapid development and developmental transparency. Hematopoeisis Zebrafish play a major role in the study of hematopoiesis. How zebrafish mend the spinal cords: If nerve tracts in the animals are damaged, certain connective tissue cells, called fibroblasts (green), migrate to the wound and form scar tissue. Faculdade de Ciências Médicas de Lisboa. Edward A. Burton, in Movement Disorders (Second Edition), 2015. According to the genome sequencing data, the zebrafish shares 70% genes with humans and more than 84% of genes that cause human genetic diseases are present in the zebrafish, making it an excellent model for studying human gene functions, especially those that cause various human genetic diseases. Because of these genetic qualities zebrafish are … Using the INSPIRE Faculty programme Dr Vimalraj and his research team is further working to develop transgenic zebrafish (which have exogenous genes added to their genome) model by use of the CRISPR/Cas9 gene-editing tool to further study the compensatory angiogenesis mechanism in tumour microenvironment Furthermore, zebrafish exhibit a rich repertoire of quantifiable behavioral responses similar to mammalian vertebrate models. Why zebrafish? Our transdisciplinary study capitalizes on the use of specific assets such as zebrafish transgenic model in conjunction with our in-depth knowledge of 4D microscopy, 3D-image modelling, physics and mathematics. The zebrafish research has gained further momentum in recent years due to two major technological breakthroughs: (1) completion of its genome sequencing (Howe et al., 2013) and (2) development of genome-editing technology (Gaj et al., 2013). Zebrafish are increasingly seen as a promising model organism in which to investigate neurodevelopment because their young, or larvae, are transparent, making it possible to image the whole brain in real time. The Mayo Zebrafish Facility plays a significant role in multiple research laboratories, serving as a critical hub for new scientists as they learn to tap into the potential of this model system. The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow family (Cyprinidae) of the order Cypriniformes. More recently, we demonstrated that the mechanical stress exerted by the blood flow on the aorta induces a series of morphogenetic signals resulting in the activation of HSC specifying genes and the down-regulation of endothelial vascular identity. The zebrafish embryo allows for rapid, non-invasive and real time analysis of bacterial infections in a vertebrate host. Zebrafish has become a favorite model of choice in the biomedical research covering a broad array of topics ranging from developmental biology and morphogenesis to neurosciences, regeneration and aging in the past decades. Jason Rihel, ... Alexander F. Schier, in Methods in Cell Biology, 2010. K.J. (Scroll down for a video on zebrafish video tracking!) Zebra fish ES cells derived from wild-type embryos (see the section on derivation of zebra fish ES cell cultures) and growing in a single well of a six-well plate are harvested in trypsin/EDTA solution (see the section on passaging the primary cultures) and suspended in LDF medium at a density of 2–3 × 106 cells/ml. Yet, following this humble beginning, why has the zebrafish developed into one of the most popular model organisms for research? The zebrafish vertebrate brain is evolutionarily conserved and exhibits many anatomical similarities to the mammalian brain (Tropepe & Sive, 2003). Due in part to the ease of husbandry, the zebrafish has been actively studied for a century in life science research. The Zebrafish International Resource Center is a non-profit organization. In the late 1960s, George Streisinger, who is considered the founding father of zebrafish research, first introduced this tiny slender fish as a vertebrate model for research on genetics and development at the University of Oregon. Due to the Covid-19 pandemic, resource distribution has been reduced and services may be intermittent. Provides the first authoritative and comprehensive treatment of zebrafish in biomedical research as part of the ACLAM series Readership Vivarium professionals maintaining zebrafish colonies, veterinarians … 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. This teleost was first described in the 1800s as an inhabitant of the Ganges River in India. The zebrafish (Danio rerio) is a fresh water fish that originates from Southeast Asia and is the premier nonmammalian vertebrate for genetics studies. Zebrafish lacking oxytocin receptors spend more time swimming solo than wildtype zebrafish do, and neurochemicals in their brains respond differently to social interactions, according to new unpublished work.. Emergence of haematopoietic stem cells in the zebrafish embryo, Head of ‘Emergence of haematopoietic stem cells and cancer’ team 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. We will contact you to make arrangements for our next available shipping date. Eirini Trompouki, ... Leonard I. Zon, in Methods in Cell Biology, 2011. The research hence shows that compensatory mechanisms could be a potential curative target for the development of effective anti-cancer treatments. Share this post. Grow incredibly fast (as much in a day as a human embryo in a month). The zebrafish has developed into an important model organism for biomedical research over the last decades. At Roche, we are excited about the zebrafish as an alternative model for supporting our '3R' efforts, the refinement, reduction and replacement of animal studies Facts and figures: Zebrafish are Zebrafish use in research has been growing steadily on the world-stage, but in South America in particular this growth is unprecedented. In the past 20 years, the zebrafish has gradually risen as one of the top model organisms for biological and biomedical research due to its biological advantages such as short generation time (2–3 months), high fecundity (∼200 eggs/clutch), in vitro development, transparent … Larval zebrafish can be housed in 96-well plates, where they can be exposed to small molecule libraries for drug discovery. The pretty stripes have nothing to do with it. Can be housed in large, tight knit groups. A.M. Shafik, D. Cifuentes, in Encyclopedia of Cardiovascular Research and Medicine, 2018. Epub 2013 Oct 31. Furthermore, zebrafish are highly social allowing these animals to be housed in high-density system racks, features that make the zebrafish amenable to high-throughput behavioral screens. These fishes have the same sequential multilineage hematopoiesis process as humans, with the same distinct lineages. Although the zebrafish was first developed as a model for developmental genetics, its utility has been quickly extended to many other fields of biological and biomedical sciences, including physiology, toxicology, disease modelling and drug development. Each female zebrafish can produce hundreds of eggs per week. Our series, Animals in Research, profiles the top organisms used for science experimentation. Zebrafish have been shown to carry highly conserved orthologues in their genome resembling many of the genes associated with various human neurological disorders. Here, we discuss inflammasome research in zebrafish … Head of ‘Emergence of haematopoietic stem cells and cancer’ teamCNRS -UMR5235-LPHI, Université de Montpellier - France, Ce site a été conçu sur la plateforme de création de sites internet, Head of ‘Emergence of haematopoietic stem cells and cancer’ team. 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. The Zebrafish may be a mere minnow, but it is being hailed throughout the research and science community as a promising scientific and biotechnological advancement tool. Wei Ge, in Encyclopedia of Reproduction (Second Edition), 2018. 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. Reproduction. The zebrafish is commonly used in research of bacterial virulence. This technique has been used extensively and successfully in other systems and it will be a useful tool for studying epigenetics in zebrafish. The use of zebrafish (Danio rerio) as a model organism began in the 1960s. 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). The prices we charge for products and services are to offset some of the actual costs we incur. It has many characteristics that make it a valuable model for studying human genetics and disease. Benefits of Zebrafish as a Research Organism. Although the main focus of zebrafish research has traditionally been on developmental biology, keeping and observing zebrafish in the lab led to the identification of diseases similar to humans, such as cancer, which subsequently became a subject for study.

The genetic underpinnings of heart development in zebrafish are highly similar to that in humans, while zebrafish presents many advantages that allow for rapid screening of candidate CHD-associated gene variants. This model has therefore provided scientists with many insights, both in blood lineage development pathways and blood disorders. Emergence of haematopoietic stem cells in the zebrafish embryo Friday 18th december 2020 11h30 to 12h30 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). Cardiovascular disease These fishes are also largely used for investigating cardiovascular diseases as they have a similar embryonic heart structure as that of human embryos. In addition, the susceptibility to many state-of-the art cell and molecular biology techniques and amenability to chemical and genetic manipulations have contributed to its increasing popularity. Zebrafish is recognized as an ideal model organism for investigating the cellular and molecular mechanisms underlying heart formation and regeneration.
