"We are linked by blood," writes Joyce Carol Oates, "and blood is memory without language." The network of blood vessels known as the vascular system connects all tissues and organs. Confocal imaging gives us the opportunity to view the vascular system by illuminating the whole body with fluorescent light and providing a translucent image of the subject. This mosaic of different confocal images gives us an entire picture of a mouse embryo. Here the vascular system, rather than appearing in a familiar blood-red, is represent by the color green. The blue color represents the DNA that will direct the embryo's growth.
