Stem cells created without embryo destruction

An East Bay stem cell research firm reports it has developed five human embryonic stem cell lines -- without the destruction of embryos.

Advanced Cell Technology, headquartered in Alameda, says the discovery has the potential to end the ethical debate over the use of embryos to derive stem cells. The process was developed using single cells removed from the embryos. They were then cultured, using proprietary methodology. The cells continued to develop and were later frozen.

The research is published today in the journal "Cell Stem Cells."
