GOTTA FIND A WAY TO GIVE THEM THEIR TOTEMS:

'Ethical' stem cell lines created (BBC, 8/23/06)

Human embryonic stem cell lines have been generated without embryos being destroyed, according to researchers.

A US team created stem cell lines by removing single cells from embryos, a process that left them intact, they report in the journal Nature.

At present, growing this type of stem cell results in embryo destruction.

The researchers say their findings may remove some of the ethical barriers to this field and provide a way of bypassing current US legislation. [...]

Using spare human IVF embryos, the researchers removed single cells from them, employing the same procedure used for pre-implantation genetic diagnosis (PGD), a technique that has been used in IVF so cells can be removed from the embryo and tested for genetic disorders.

The process, said the team, leaves the embryo intact, enabling it to continue and grow into a healthy foetus.

Of the 16 embryos used, they developed two long-term stem cell lines, which, Professor Lanza said, were "genetically normal and able to generate all of the cell types of the body".
