The U.S. House conceded a legislation that would lift restrictions on embryonic stem-cell research. Thus, setting up a confrontation with President Bush, who was not in favor of it. The research is quite controversial because it involves stem cells taken from fertilized human eggs, or embryos, which are destroyed in the process of extracting the stem cells. Anti-abortion lawmakers and like-minded constituents believe their taxes should not fund such research. While the supporters asserted that, it is done on embryos that would otherwise be discarded from fertility clinics. In addition, they mention the emergence of stem cell research alternatives that do not require the destruction of embryos. Minority Leader John Boehner said, ‘I support stem cell research with only one exception – research that requires killing human life. Taxpayer-funded stem cell research must be carried out in an ethical manner in a way that respects the sanctity of human life. Fortunately, ethical stem cell alternatives continue to flourish in the scientific community.’ Researchers stated the most promising evidence supports embryonic stem cells that one day they might be used to grow replacements for damaged tissue, such as new insulin-producing cells for diabetics or new nerve connections to restore movement after spinal injury.
