The release of BP into aquatic ecosystems and the potential toxic effects on aquatic organisms are becoming major concerns. One study profiled 38,731 cells from 694 embryos over multiple stages and reconstructed the patterns of gene activity and cell divisions that coordinate development of the body plan (Farrell et al., 2018). Zebrafish are also amenable to manipulation of brain activity: optog… Regarding neuroscience studies, ExM enables the tracing of cellular processes in the zebrafish brain, as well as the imaging of synapses and their biomolecular content and organization. Imaging in Developmental Biology: A Laboratory Manual, a new volume in Cold Spring Harbor Laboratory Press’ Imaging series, presents a comprehensive set of essential visualization methods. Many thanks to our guest blogger Katherine Rogers from the Friedrich Miescher Lab of the Max Planck Society. Renee Wei-Yan Chow, Julien Vermot, The rise of photoresponsive protein technologies applications in vivo: a spotlight on zebrafish developmental and cell biology, F1000Research, 10.12688/f1000research.10617.1, 6, (459), (2017). The manual features primers on live imaging of a variety of standard model organisms including C. elegans, Drosophila, zebrafish, Xenopus, avian species, and mouse. Non-random integration into specific pre-determined regions is also possible using an alternative approach that exploits the bacteriophage integrase phiC31. Here, we explore the application of proExM to zebrafish, a genetically tractable vertebrate that is transparent throughout early life and, accordingly, has proven to be a useful model for neuroscience and developmental biology . Zebrafish have transparent embryos that develop outside the mother which is an important feature for microscopy. Zebrafish embryos exhibit unique characteristics, including ease of maintenance and drug administration, short reproductive cycle, and transparency that permits … "Single-cell reconstruction of developmental trajectories during zebrafish embryogenesis.

Tools for gene manipulation together with information about the genome are powerful resources for investigating any biological process. [Article in Chinese] Xin SC(1), Zhao YQ, Li S, Lin S, Zhong HB. Creating transgenic organisms by introducing foreign DNA into the genome is useful for a variety of applications. We archive and distribute high quality plasmids from your colleagues. For example, neuronal activity can be tracked in whole brains of swimming, actively learning larvae, providing unprecedented views into cognitive processes like decision making (Kim et al, 2017). Zebrafish are also popular outside of developmental biology, and are particularly well-suited for neuroscience investigations. In the 1990’s, two revolutionary large-scale random mutagenesis screens produced ~1,500 zebrafish mutants that are still used in labs across the globe (Nüsslein-Volhard et al., 2012). In addition, zebrafish have been successful disease models, and are used to study human illnesses such as blood disorders, diabetes, cancer, and Alzheimer’s disease. Adult zebrafish (Danio rerio). Frontiers in Cell and Developmental Biology ... As some toxicity was observed with VP-EL222 it was further optimized for applications in zebrafish by exchanging the VP16 transcriptional activation domain with TA4, which is better tolerated in zebrafish, resulting in TA4-EL222 (TAEL) (Distel et al., 2009; Reade et al., 2017). "Reconstruction of zebrafish early embryonic development by scanned light sheet microscopy."
