But like the medieval alchemists, today's cloning and stem cell biologists are working largely with processes they don't fully understand: What actually happens inside the oocyte to reprogram the nucleus is still a mystery, and scientists have a lot to learn before they can direct a cell's differentiation as smoothly as nature's program of development does every time fertilized egg gives rise to the multiple cell types that make up a live baby.

The results help fill in the scientific puzzle kicked off by Dolly's cloning, which proved that mammalian egg cells were capable of dissolving the genetic roadblocks that limit the potential of most adult cells to give rise to only a single type of tissue — that of the organ from which they hail — whereas embryonic stem cells have the potential to become virtually any kind of body tissue.
