Scientists have traced the family tree of about 1.3 million cells as a mouse embryo grew from a single fertilized egg into an animal with its major organs in place. The study, published Oct. 8 in Science, used a genetic recording tool called DNA Typewriter that writes a running record of cell divisions into the cells' own DNA.
