The low cost, small size, and external development of zebrafish make it an excellent model for vertebrate development biology. They are also very cheap; however, they do require more space than other model organisms such as flies. 2004 Oct;17(5):461-70. doi: 10.1111/j.1600-0749.2004.00189.x. The creation of critical genetic reagents, coupled with the rapid progress of the zebrafish genome initiative directed by the National Institutes of Health, are bringing this model system to its full potential for the study of vertebrate biology, physiology and human disease. Since they are naturally found in ponds, their ideal conditions can be easily replicated. Through a powerful combination of genetics and experimental embryology, significant inroads have been made into the regulation of embryonic axis formation, organogenesis, and the development of neural networks. NIH Similar to mice and fruit flies, zebrafish can be used for genetic analysis. Advantages of using Zebrafish as a Model Organism. Adult zebrafish are small in size, they grow quickly, and they breed readily. Zebrafish (Danio rerio) is emerging as a popular model vertebrate system, which resembles mammals in its development. Among the model organisms, the zebrafish (Danio rerio) is one of the best leading … Functional genomics tools for the analysis of zebrafish pigment. 2020 Feb 14;11:32. doi: 10.3389/fphar.2020.00032. Copyright © 2000 Elsevier Science Ltd. All rights reserved.  |  Print 2013. In recent years, zebrafish has become a favorite organism of those who wish to study vertebrate development for the following reasons: Zebrafish have large broods. Small size and speedy growth: The same traits that make zebrafish popular pets also make them good model organisms. A Phenotypic and Genotypic Evaluation of Developmental Toxicity of Polyhexamethylene Guanidine Phosphate Using Zebrafish Embryo/Larvae.  |  The second reason for the rapid expansion of zebrafish colonies in research labs is the optical transparency of zebrafish embryos. HHS As a vertebrate model organism, zebrafish provide a variety of advantages. Nevertheless, there is still lack of detailed reports about usage of the zebrafish as a model in veterinary medicine. One unavoidable disadvantage of a relatively new model organism is just that; it is new. Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies, as well as research in toxicology and genomics. Given this, it may be surprising how little is known about the mechanism that zebrafish use to determine sex. The zebrafish (Danio rerio) is a tropical. Zebrafish have transparent embryos that develop outside the mother which is an important feature for microscopy. Techniques for large-scale genome mutagenesis and gene mapping, transgenesis, protein overexpression or knockdown, cell transplantation and chimeric embryo analysis, and chemical screens have immeasurably increased the power of this model organism. Zebrafish are the most widely used non-mammalian vertebrate organism, with thousands of laboratories devoted to zebrafish research worldwide. Abstract In the last 30 years, the zebrafish has become a widely used model organism for research on vertebrate development and disease. Here it's development is explained. A common approach to unravel the gene networks that drive biology is to examine the consequences of manipulating genes. Neurotoxicol Teratol. Zebrafish are becoming an increasingly popular model organism for studying vertebrate development, but it is still a relatively new model organism. This site needs JavaScript to work properly. The Zebrafish is a widely used vertebrate model for development, it was first established as a useful model organism by George Streisinger, Zebrafish are as commonly used as rats and mice. The Zebrafish, Danio rerio, is tropical freshwater fish and a very popular model organism for scientific research in the fields of development, vertebrate processes, genetics, and more. Front Pharmacol. They lay large numbers of externally developing, transparent embryos, which we can easily manipulate using genetic, molecular and … Birth Defects Res C Embryo Today.  |  Although these models have significant advantages, they are also expensive to maintain, difficult to manipulate embryonically, and limited for large-scale genetic studies. 00:06:13.15 So many vertebrates have organs that are not seen in these invertebrate model organisms 00:06:18.01 and also many genes that are specific to vertebrate species. It is also notable for its regenerative abilities, and has been modified by researchers to produce many transgenic strains. The question should drive which model organism to use, not vis-versa.” The zebrafish (Danio rerio) has become known as an excellent model organism for studies of vertebrate biology, vertebrate genetics, embryonal development, diseases and drug screening. Over the last several decades zebrafish (Danio rerio) has become a major model organism for the study of vertebrate development and physiology. R01 DK054508/DK/NIDDK NIH HHS/United States, T32 CA 90095/CA/NCI NIH HHS/United States. PDF | Keladi tikus (Typhonium flagelliforme (Lodd.) Studies involving Zebrafish have been important in many fields of research including oncology, regeneration and particularly embryonic development. Zebrafish. The use of zebrafish as a model organism was pioneered to overcome some of the difficulties that plague other vertebrate model organisms such as in utero development, low offspring number, lack of genetic tractability, and high maintenance costs. They can be easily maintained. The zebrafish is one such model that holds tremendous promise to increase our understanding of vertebrate biology. Ding Y, Liu W, Deng Y, Jomok B, Yang J, Huang W, Clark KJ, Zhong TP, Lin X, Ekker SC, Xu X. Circ Res. Maintenance Firstly, Zebrafish are very robust and easy to maintain. Discoveries made in zebrafish can be further validated in mammals. “Sean Burgess is a great example of someone who has recently switched from yeast to a vertebrate—zebrafish—so that is a huge leap,” says Draper. Evaluation of the Developmental Toxicity Induced by E804 in Zebrafish Embryos. Overall, the development and use of multicellular vertebrate organisms, such as zebrafish and Xenopus embryos, as in vivo drug discovery tools has expanded our possibilities to investigate the chemical universe for novel small bioactive molecules that could serve as lead compounds for drug development and therapeutic intervention. Given the physical and ethical problems with performing experiments on human patients, biomedical research has focused on using model organisms to study biologic processes conserved between humans and lower vertebrates. The zebrafish, Danio rerio, a small, tropical freshwater species native to Pakistan and India, has become a National Institutes of Health‐sanctioned model organism and, due to its many advantages as an experimental vertebrate, it has garnered intense interest from the world's scientific community. The zebrafish model nicely complements these deficiencies in mammalian experimental models. Zebrafish has many advantages as a model of human pediatric research. eCollection 2019. The principle objective of this PA is to continue to promote the zebrafish as an animal model for the study of development, organ formation, behavior, aging, and disease research. Conclusion: Zebrafish is a positive and versatile model the vertebrate organism, bestowing a means to model a gene function, drug discovery, toxicology, cancer studies, development of various organ system, human diseases and disorders, etc. Examples of model invertebrate organisms are the fruit fly and nematode worm, while model vertebrates include the medaka, zebrafish, frog, chick, mouse, and rat. The low cost, small size, and external development of zebrafish make it an excellent model for vertebrate development biology. eCollection 2020. Large-scale genetic screens have identified hundreds of mutant phenotypes, many of which resemble human clinical disorders. 2004 Nov-Dec;26(6):709-18. doi: 10.1016/j.ntt.2004.06.015. Epub 2013 Jan 2. The zebrafish (Danio rerio) is a powerful model organism for the study of vertebrate biology, being well suited to both developmental and genetic analysis. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The zebrafish is a model organism used to study the development of vertebrates.
