Three teams of scientists said yesterday they had coaxed ordinary mouse skin cells to become what are effectively embryonic stem cells without creating or destroying embryos in the process -- an advance that, if it works with human cells, could revolutionize stem cell research and quench one of the...

WASHINGTON -- A procedure that encourages an egg to begin embryo development without being fertilized could suggest a new way to produce stem cells, at least for certain patients.

NEW YORK -- Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.
