The Bush administration is expected to decide soon whether to provide federal funds for research using embryonic stem cells. Some people opposed to funding this work say scientists have shown that adult stem cells are just as powerful, and that embryonic research isn't needed. This hour, we'll take a look at the science of stem cell research. What kinds of tissues have been derived from adult stem cells? Can they supply us with all the tissues and information we need to fight disease, or is embryonic stem cell research still needed? Plus, we'll get an update on the Bush administration's impending decision.
