{{merge|Embryonic stem cells}}'''Embryonic stem cell''' research is the utilization of [[stem cells|stem cells]] from [[embryo]]s which can then be grown in a laboratory culture and produce specialized cells to treat [[disease]]s or used for research purposes. The most common source of such cells is discarded embryos at [[fertility clinic]]s - the process of [[IVF]] typically produces two or three 'leftover' embryos for each treatment, which are usually discarded. The use of embryonic stem cells in medicine has met with some controversy, particularly from the [[pro-life]] movement that is concerned about the destruction of embryos that they believe constitute human life.<ref>http</ref>
'''Adult stem cell''' research is similar except it does not use destroyed embryos, and instead is based on stem cells that can be taken from adults. These cells are less versatile than those harvested from discarded embryos, but they do not raise the associated [[ethics|ethical]] dilemmas. Unfortunately, adult embryonic stem cells are of little value to science as a whole.
*President Bush's refusal of [[federal funding]] for new embryonic stem cell lines didn't halt major stem-cell advances, any more than the prohibition against life-threatening research on human subjects, such as the infamous Tuskegee Study of Untreated Syphilis in the Negro Male, stopped the advance of medical treatments.

*On March 9, 2007 Barack Obama repealed President Bush's ban on federal funding for embryonic stem cell research. <ref>http</ref>This was a campaign promise and leads to the expectation that he will be one of the most pro-choice Presidents in U.S. history.<ref></ref>
