Real-time four-dimensional (4D, xyzt) imaging of cultured avian embryos is an ideal method for investigating the complex movements of cells and tissues during early morphogenesis. While methods that transiently label cells, such as electroporation, are highly useful for dynamic imaging, they can also be limiting due to the number and type of cells that can be effectively targeted. In contrast, the heritable, stable, and long-term expression of a fluorescent protein driven by the exogenous promoter of a transgene overcomes these challenges. We have used lentiviral vectors to produce several novel transgenic quail lines that express fluorescent proteins either ubiquitously or in a cell-specific manner. These lines have proven to be useful models for dynamic imaging and analysis. Here, we provide detailed protocols for generating transgenic quail with the emphasis on producing high titer lentivirus, effectively introducing it into the early embryo and efficiently screening for G1 founder birds.
