I am no biologist, but I can freaking read. And I am tired of every one talking about stem cell research, and using embryos for stem cells. Embryos may be the easiest way to get stem cells (I am assuming that I have never read that to my knowledge), but they are not the moral way. The easiest way to stop crime is kill all criminals, but that is not the moral way to stop crime.
So I am going to give a lot of really interesting links, and you can make an informed judgment on stem cells. As you are flipping through the articles, please check the date which it was written all may not be recent.
Enjoy and you don't have to read all of them, but there are some very interesting ones (well from only reading the titles they are interesting).
It all started here.....
Hopkins Research Team Cultures Long-Awaited Human Embryonic Stem Cells
New Technique Boosts Potential For Growing Stem Cells
Adult Mouse Bone Marrow Stem Cells Can Become Cells Of The Nervous System

AAAS Urges President Bush To Fund Stem-Cell Research
The American Association for the Advancement of Science (AAAS) sent a letter to President George W. Bush expressing its strong support for federal funding of research using human stem cells from embryonic, fetal and adult sources
What you can get stem cells from sources other than embryos?!?!?!?

Scientists Discover Unique Source Of Postnatal Stem Cells in 'Baby' Teeth
Ok, that is it I am done.
In short, why use embryonic stem cells, you will have to coax them to the needed tissue anyways, for most uses the adult stem cells are closer to the tissue you want.
Though we might find a tissues that must come directly from embryonic stem cells, we have made techniques that can grow those efficiently.
