When an embryo is days old, its powerful embryonic stem cells grow without limit, turning themselves into any cell the body needs.

But as these cells mature, their scope is limited to the function defined for them. For years, scientists have explored ways to return mature cells into an embryonic-like, or pluripotent, state.
