New methods add twist to stem cell debate
From http://www.abc.net.au/science/news/stories/s1483682.htm
Two alternative methods for making embryonic stem cells work in mice and might lead to a less controversial way to grow human ones, US researchers report.
...
Dr Robert Lanza and colleagues took a cell from an embryo when it only had eight cells, and used it as a source of stem cells. The remaining seven-cell embryo developed normally.
...
A second team at the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology (MIT) genetically disabled a gene in a mouse cell that is important to allow a fertilised egg to become an embryo.
The scientists then cloned the cell, grew an embryo, and extracted stem cells from it.

This looks pretty interesting... Found it while Stumbling today. I'm about as pro-life as they come an am against anything that threatens the life of an embryo, fetus, or "person". It would be awesome if they could do this in humans. In 50 years every person could have custom grown organs waiting for them at the hospital. That is pretty cool.
