Eggan's technique, which is the subject of a paper in the current issue of Nature, creates stem cells specific to a particular disease, like cancer or diabetes, without a supply of human egg cells.

FORBES: Stem Cell Science Heats Up

Like natural selection and germs, the discovery of cancer stem cells illustrates how the most fruitful scientific findings are often not those of individual experiments, however intriguing, but those that organise knowledge into theory.
