The Stem Cell Challenge

The Coalition for the Advancement of Medical Research is reprinting a very good Scientific American article that introduces and explains the fundamental science of embryonic and adult stem cell research. What are the hurdles, what has been accomplished to date, and how does it all work to regenerate the human body? If you feel that you would like a better grasp of the basics, then this would be a good place to start. Scientists have a great deal of work yet to accomplish, but as the article reminds us, "how long it will take for any [embryonic stem cell] therapies to be tested in humans will be determined as much by politics as by the remaining scientific questions."
