A Simple Blood Vessel Imaging Protocol for Live Zebrafish Larva.
Zebrafish larva is a simple model system to study blood vessel development because of its excellent optical properties. Current methods to study blood vessels in zebrafish involve utilizing either blood vessel-specific transgenic lines or specialized techniques such as microangiography and video capillaroscopy. In this study, we have developed a simple protocol using ImageJ to observe the blood vessels of live zebrafish larva at different developmental stages, namely 1- to 4-day postfertilization (dpf). To validate this protocol, we treated 1 dpf zebrafish embryos with 100 μM quercetin, and analyzed the impaired development of subintestinal vein in the quercetin-treated 3 dpf larvae.
期刊介绍:
Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease.
Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage.
Zebrafish introduced the new section TechnoFish, which highlights these innovations for the general zebrafish community.
TechnoFish features two types of articles:
TechnoFish Previews: Important, generally useful technical advances or valuable transgenic lines
TechnoFish Methods: Brief descriptions of new methods, reagents, or transgenic lines that will be of widespread use in the zebrafish community
Zebrafish coverage includes:
Comparative genomics and evolution
Molecular/cellular mechanisms of cell growth
Genetic analysis of embryogenesis and disease
Toxicological and infectious disease models
Models for neurological disorders and aging
New methods, tools, and experimental approaches
Zebrafish also includes research with other aquarium species such as medaka, Fugu, and Xiphophorus.
