Zebrafish embryos, because of the optical clarity, small size, and fast development, can be easily used to (1) study osteogenesis evaluating differentiation, matrix deposition activity, and cross-talk of skeletal cells, (2) create and isolate mutants modeling human bone diseases, and (3) test in high-throughput screenings new chemical compounds for the ability to revert bone defects. Rapid whole brain imaging of neural activity in freely behaving larval zebrafish (. , which generated and analysed 132 different mutants of SCZ-risk genes, showed that hyperlocomotion was sometimes observed in a number of these fish. A comparison between diploid and triploid zebrafish larvae | … 3F, Supp. developed in larvae. GEMMA MICRO 75 can be used as a start feed for newly hatched zebrafish larvae. Zebralab (ViewPoint, Montreal, Canada) recordings were made in a separate testing room with similar environmental conditions as the fish facility. Sound generation in zebrafish with Bio-Opto-Acoustics. AB wild-type (WT) and myd88 −/− mutant zebrafish larvae were obtained from our experimental facilities, where zebrafish are cultured following established protocols (Nusslein-Volhard and Dahm, 2002; Westerfield, 2000). PS NPs decreased the survival of immunosuppressed or infected larvae. The main effect of PFOS in zebrafish larvae is an uninflated swim bladder. Quantifying Liver Size in Larval Zebrafish Using Brightfield Microscopy Article doi: 10.3791/60744. Phenylthiourea (PTU) is commonly used for inhibiting melanization of zebrafish embryos. Zebrafish larvae are frequently used as vertebrate disease models and are associated with several advantages, including high fecundity, optical translucency and non-protected status prior to 5 days post-fertilisation. Fig. … … This paper has been recommended for acceptance by Maria Cristina Fossi. Panier T, Romano SA, Olive R, Pietri T, Sumbre G, Candelier R, Debrégeas G. Front Neural Circuits. By assaying wildtype zebrafish in a variety of conditions, we determined optimal parameters that … Fig. Zebrafish are vertebrates often used for in vivo studies, because they are relatively small in size and the embryonic and larval development is ex utero and fast, since within 5 days post-fertilization (dpf), all major organ systems are formed (Kimmel et al., 1995). Nanoparticles mainly accumulated in the gut, where they triggered reactive oxygen species, decreased expression of the antioxidant gene catalase and induced migration of immune cells. These reactions are reduced after ablation of the lateral line sensory organ and mimicked by local water motions. PS NPs colocalized with lysosomes and raised the pH of these organelles. On … Adult zebrafish were maintained in a recirculating water system on a 12:12 h light-dark cycle and. Rearing of embryos and larvae represents a key issue in a zebrafish facility. Imaging voltage in zebrafish as a route to characterizing a vertebrate functional connectome: promises and pitfalls of genetically encoded indicators.

Seeing the whole picture: A comprehensive imaging approach to functional mapping of circuits in behaving zebrafish. 22 Specific visual … The impact of PS NPs was studied at the cellular, molecular and systemic levels.  |  (a) A representative image of size determination of zebrafish larvae. We synthesized TBBPA-S from the biotransformation of TBBPA by the zebrafish, as follows: 60 zebrafish larvae (3 dpf) were placed in a Petri dish (60 mm) with 9 ml of E3, and treated with 9 μl of 1mM TBBPA dissolved in DMSO, or DMSO only (control). This technique … Integrative whole-brain neuroscience in larval zebrafish Curr Opin … However, precise specimen immobilization and … Our results revealed that the cellular distribution differed depending on the particle size: the 50 nm PS NPs were more homogeneously distributed in the cytoplasm and the 1 μM PS NPs more agglomerated. The size ratio of zebrafish adults and larvae (10:1) is comparable to that of other pairs of predator and prey fish (for a review, see Godin, 1997). Overexpression of seven genes and knockdown of five of these genes resulted in a reduction of head size in zebrafish larvae. (A) Representative ERG recordings to a 0.5 second white light stimulus are shown at four different time points: at 9:00 AM, when the ambient lights are turned ON; 11:00 PM, shortly before the lights are turned OFF; 2:00 AM, after the lights have been OFF for 3 h; and at 9:00 AM the next … HHS Neuroscience. In The gape size of 120 hpf larvae allows them to consume smaller diameter Paramecium and rotifers, but usually not Artemia. Larvae that were only exposed early (1-48 hpf) or late (120-144 hpf) during development showed no effects on the studied endpoints. Adult zebrafish exhibit rapid suction-feeding strikes (t MO =14.9±6.2 ms), which are customary of other piscivores like bluegill sunfish or largemouth bass (Higham et al., 2006). 7 The easy accessibility to the hearing organ, the small size and the structural and functional similarities between zebrafish and mammalian hair cells, make zebrafish a valuable animal model for … 6T … Epub 2014 Nov 27. Time course of zebrafish adipocyte appearance in larvae from 6 to 30 days postfertilization (dpf). With the development of sensitive genetically encoded calcium indicators, this has extended to the whole-brain imaging of neural activity with cellular resolution. The zebrafish has emerged as a powerful model organism for studying intestinal development 1-5, physiology 6-11, disease 12-16, and host-microbe interactions 17-25.Experimental approaches for studying intestinal biology often require the in vivo introduction of selected materials into the lumen of the intestine. In our study, larvae were maintained at a relatively low density to maximize access to food, yet we also still found a significant variance in SL after 9 dpf, and the range increased as the fish got older (Fig. Zebrafish typically vary greatly in size. Their small size, high fecundity, and rapid development allow for more high-throughput experiments compared to other vertebrate models. A study by Thyme et al. In the zebrafish model, the small larval size and conserved morphology of the pronephros offers a general applicability for high‐throughput assays as larvae can easily be treated and screened in the 96‐well format as it has been shown before for modulators of polycystic kidney disease using a morpholino‐based genetic zebrafish model 24 or a developmental drug nephrotoxicity assay … These effects at cellular level agree with the results in vivo, since lysosomal alkalization increases oxidative stress and vice versa. The zebrafish and zebrafish larva is a suitable model organism for drug discovery and development. Larvae raised in isolation perform stronger escape reactions to a proximate conspecific. As homozygous mutant survival was low (i.e. Constantin L, Poulsen RE, Scholz LA, Favre-Bulle IA, Taylor MA, Sun B, Goodhill GJ, Vanwalleghem GC, Scott EK. The main endocytic mechanisms for the uptake of NPs were dynamin-dependent internalization for the 50 nm NPs and phagocytosis for the 1 μm nanoparticles. Imaging vessels in later-stage larval or juvenile zebrafish is usually very technically challenging owing to the depth and thickness of the tissues, but since the superficial lymphatic network is extremely close to the surface of the animal it is feasible to acquire high-resolution images to capture events such as trafficking of immune cells in these lymphatics, even at 35 dpf (Fig. 2016 Jun;30(2):80-8. doi: 10.1080/01677063.2016.1180384. Only TBBPA-S was … Dead zebrafish were removed three times a day. In both cases, degradation in lysosomes was the main fate of the PS NPs, which generated alkalinisation and modified cathepsin genes expression. However, before 6 dpf, their visual system does not fully respond to visual stimuli (Huang & Neuhauss, 2008). These include qualitative characteristics (e.g., caudal fin shape), as well as continuous and meristic quantitative traits (e.g., body height and fin ray counts, respectively). Copyright © 2018 Elsevier Ltd. All rights reserved. 250 µm also is the average size of rotifers, which are frequently used for rearing zebrafish larvae (Aoyama et al., 2015. NIH Abstract. This fact could be explained by the mechanical disruption and/or the oxidative damage caused by these NPs that increase their susceptibility to pathogens. Transition to GEMMA MICRO 150 can be done … To optimize diet particle size for ingestion by zebrafish larvae, Danio rerio, a series of diet selection experiments were carried out using two different length classes: 5-day-old, first feeding larvae with a mean standard length (MLs) of 3.8 mm and 15-day-old larvae with MLs of 5.2 mm.For this purpose, crosslinked protein-walled capsules with five different size classes (≤20, … February 2nd, 2020 • Srishti Kotiyal* 1, Alexis Fulbright* 1, Liam K. O'Brien* 1, Kimberley J. Evason 1. Thus an estimate of the number of larval zebrafish from day 4 - 7dpf should be included in Animal HHMI/Howard Hughes Medical Institute/United States. AB - Due to their size and optical clarity, zebrafish embryos have long been appreciated for their usefulness in time-lapse confocal microscopy. Due to their small size and transparency, zebrafish larvae are amenable to a range of fluorescence microscopy techniques. Drug discovery in whole-organisms such as zebrafish is a promising approach for identifying biologically-relevant lead compounds. The distribution and uptake of PS NPs in the ZF4 cell line were size dependent. Each horizontal strip of four boxes indicates fish at the indicated standard length (SL). zebrafish larvae can be conditioned to avoid one side of the tank by repeatedly pairing this position with electroshock. NLM very small sample size), we focused the majority of our analysis on heterozygotes, thus investigating the effects of cacna1da haploinsufficiency on larval zebrafish behaviour and electroencephalography (EEG) patterns. 2020 May 20;40(21):4130-4144. doi: 10.1523/JNEUROSCI.0049-20.2020. Zebrafish larvae are an attractive alternative vertebrate system to study the metabolic effects of alcohol owing to their large clutch size and rapid generation time, in conjunction with the simple culture system approach and the ability to manipulate the externally developing larvae. Zebrafish embryos are virtually transparent during development, allowing visualization of internal organs … 2.3.1. Fast functional imaging of multiple brain regions in intact zebrafish larvae using selective plane illumination microscopy. The contamination of the aquatic environment by plastic nanoparticles is becoming a major concern due to their potential adverse effects in aquatic biota. Therefore, in-depth knowledge of their uptake, trafficking and effects at cellular and systemic levels is essential to understand their potential impacts for aquatic species. Whitebait is a marketing term for the fry of fish, typically between 25 and 50 millimetres long.  |  This technique has been used to study brain-wide population dynamics accompanying sensory processing and sensorimotor transformations, and has spurred the development of innovative closed-loop behavioral paradigms in which stimulus-response relationships can be studied. Diploid and triploid zebrafish larvae are morphologically indistinguishable at 5 dpf (Fig 6B and 6C). Zebrafish Melanoma Transplants Disseminate Faster in tert Mutant Larvae. Feeding can begin on 5 days post-fertilization. Interestingly, a recent study showed that movement restraint of zebrafish larvae reduces proliferating cells and neurogenesis in the forebrain without affecting the size of the forebrain at 6 dpf, but also reduces the size of the forebrain at a later stage (9 dpf) (Hall & Tropepe, 2018). Zebrafish larvae are suitable in vivo models for toxicological and pharmacological screens due to their transparency, small size, ex utero development, and genetic and physiological similarity to humans. Despite this, neuroscientists have only recently begun to use these animals to study memory. Request PDF | Are acute and acclimated thermal effects on metabolic rate modulated by cell size? Two-photon imaging of neural population activity in zebrafish. Altered brain-wide auditory networks in a zebrafish model of fragile X syndrome. The small size benefits especially analyses of whole-body immune responses or infection patterns using technologies such as in vivo imaging (which can be conducted to cellular resolution), whole-mount in situ hybridization or whole-mount … Four concentrations (1/10 MNLC, 1/3 MNLC, MNLC and LC 10) of tebuconazole were used to assess hepatotoxicity. These authors equally contributed to this work. (b) The larvae hatching rate of fertilized zebrafish eggs 48 h after exposure to medium‐covered plasma treatment. 14 The receptive field size in the optic tectum is reported to decrease between 14 and 20 dpf, providing a potential neuronal mechanism for refined visual behaviors during this time period. Larval zebrafish ( Danio rerio ) of three different age classes (‘yolk-sac’ larvae, 96 h; ‘swim-up’ larvae, 9 days old; and ‘free-swimming’ larvae, 21 days old) were trained for 2, 6 and 11 days, respectively, to swim at 0 body lengths per second ( BL s–1), 2 BL s–1 and 5 BL s–1. The fish also develop rapidly, and researchers can simply add drugs to the water to test the effects. Zebrafish larvae. Zebrafish larvae have a variety of such traits that are visible at relatively low magnification under a stereomicroscope with brightfield transmitted or incident illumination. To optimize diet particle size for ingestion by zebrafish larvae, Danio rerio, a series of diet selection experiments were carried out using two different length classes: 5-day-old, first feeding larvae with a mean standard length (MLs) of 3.8 mm and 15-day-old larvae with MLs of 5.2 mm. At 6 days post fertilization, effects on survival, hatching, swim bladder inflation and size, larval length and swimming performance were assessed. These and other applications of zebrafish larvae may greatly benefit from efficient methods to measure memory in the early developmental stages. Epub 2020 Apr 10. eNeuro. As demonstrated through ongoing research programmes, the zebrafish model enables researcher… Despite that the use of larval zebrafish is rapidly increasing in research on brain, cognition and neuropathologies, it is unknown whether larvae possess recognition memory and whether the NORt can be used to assess it.

Nat Commun. Larval zebrafish possess several experimental advantages for investigating the molecular and neural bases of learning and memory. In recent years, zebrafish have become commonly used as a model for studying human traits and disorders. 50 Embryos are kept in embryo medium (often containing 0.5 mg/l methylene blue, to reduce fungal infections), at a stocking density of up to 100 embryos/ 35 ml … BMC Biol. Select a stage name below to get a detailed description and images. Furthermore, other groups have shown that zebrafish larvae can exhibit spontaneous ICH. Due to their small size and transparency, zebrafish larvae are amenable to a range of fluorescence microscopy techniques. As a vertebrate with 70% genetic homology with humans, it can be predictive of human health and disease, while its small size and fast development facilitates experiments on a larger and quicker scale than with more traditional in vivostudies, including the development of higher-throughput, automated investigative tools. Although zebrafish can detect and pursue small prey by 4 dpf, 21 preflexion larvae do not respond to biological motion, a complex and salient visual feature of social behavior. 2013 Aug 15;62(3):255-67. doi: 10.1016/j.ymeth.2013.05.016. Therefore, like in ApoE knockout mice, BaP may exert cardiovascular toxicity in zebrafish larvae … Here we show how to fix zebrafish larvae, dissect the tissues surrounding the liver, photograph livers using bright-field microscopy, measure liver area, and analyze results. More recently, microscopes have been developed that allow whole-brain calcium imaging in freely swimming and behaving larvae. Imaging vessels in later-stage larval or juvenile zebrafish is usually very technically challenging owing to the depth and thickness of the tissues, but since the superficial lymphatic network is extremely close to the surface of the animal it is feasible to acquire high-resolution images to capture events such as trafficking of immune cells in these lymphatics, even at 35 dpf (Fig. To study the consequences of cell size for whole-organism metabolic rate, we compared diploid and triploid zebrafish larvae differing in cell size. sample size was used in the studies, ranging from 3 to 30 zebrafish per experimental group. After recordings, all larvae were returned to the housing facility. doi: 10.7554/eLife.28158. Brain-Wide Mapping of Water Flow Perception in Zebrafish. It would be informative to examine whether and how maternal starvation and cortisol treatment … In this review, we highlight the technologies underlying whole-brain functional imaging in zebrafish, provide examples of the sensory and motor processes that have been studied with this technique, and discuss the need to merge data from whole-brain functional imaging studies with neurochemical and anatomical information to develop holistic models of functional neural circuits. In this work, zebrafish (Danio rerio) was used as a model and our aims were: i) to determine the distribution, uptake, trafficking, degradation and genotoxicity of polystyrene (PS) NPs of different sizes in a zebrafish cell line; ii) to study PS NPs accumulation, migration of immune cells and genotoxicity in larvae exposed to PS NPs; and iii) to assess how PS NPs condition the survival of zebrafish larvae exposed to a pathogen and/or how they impact the resistance of an immunodeficient zebrafish. This dataset contains raw data of gene expression levels, cell size, cell number, growth, development and swimming performance of diploid and triploid larval zebrafish, used for analyses and figures of the PLOS ONE paper: Triploidy in zebrafish larvae: effects on gene expression, cell size and cell number, growth, development and swimming performance. Kibat C, Krishnan S, Ramaswamy M, Baker BJ, Jesuthasan S. J Neurogenet. Whereas imaging methods have advanced greatly over the last two … Although this is an imprecise stage for zebrafish it can be approximated at 72 hours post fertilization. However, high content imaging of zebrafish at cellular resolution is challenging due to the difficulty in orienting larvae en masse such that the cell type of interest is in clear view. Here, we tested a NOR procedure in zebrafish larvae of 7-, 14- and 21-days post-fertilization (dpf) to investigate when recognition memory first appears during … Larval zebrafish are genetically tractable, easy to manipulate, and can be generated in large numbers.
