Fusion technique resets adult skin cells to embryonic state ...

... as seen herein.

Eggan's work raises the possibility that scientists may one day be able to make human embryonic stem-cell lines tailored to individual patients without first having to create an embryo clone of the patient: researchers could simply reprogramme a patient's skin cells.

But this isn't possible yet. The hybrid cells made by Eggan contain twice the amount of DNA found in normal cells, and so can't be transplanted into the body for therapy. Eggan thinks it should be possible to overcome this problem.

Two sets of DNA? Hmm ... ever heard of radiodurans? Are you thinking what I'm thinking, Pinky?
