Stem Cell Breakthrough: No More Need to Destroy Embryos?

Publication: National Geographic News   Date: August 23, 2005   View Article

Scientists have turned an ordinary skin cell into what appears to be an embryonic stem cell. The process may eventually eliminate the controversial step of destroying human embryos for stem cell research.

The new technique involves fusing a skin cell with an existing, laboratory-grown embryonic stem cell. The fused, or hybrid, cell is “reprogrammed” to its embryonic state, Harvard University scientists report in the journal Science.
