GENEVA - Swiss voters have overwhelming backed a proposal to allow stem-cell research on human embryos. The new law won the support of more than 66 per cent of voters.

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.

Researchers reported Thursday that they had cultivated a colony of human embryonic stem cells from an apparently dead embryo, a strategy some have suggested might be less controversial than conventional approaches that require the destruction of living embryos.

Researchers at the University of Pennsylvania School of Veterinary Medicine have identified the growth factors essential to allow spermatogonial stem cells -- the continually self-renewing cells that produce sperm -- to exist in culture indefinitely.

Mouse embryos created through a "virgin birth" process called parthenogenesis show that egg cells can be a source of valued embryonic stem cells, researchers said on Thursday.

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.

Researchers have taken ordinary skin cells from a mouse and reprogrammed them to look and act like embryonic stem cells in a long-promised experiment that provides an alternative way to get the valued and controversial cells.

Human egg cells can be tweaked to give rise to valued stem cells that match the tissue types of many different groups of people, U.S. and Russian researchers reported on Wednesday. They said the stem cells they have created from unfertilized human eggs look and act like embryonic stem cells.
