See the Editorial in the New England Journal of Medcine by physician Dr. Susan Okie "Stem-Cell Politics" New England Journal of Medicine Stem Cell Politics because it worth reading as a  rational argment to allow stem cell research. The Bush adminstration’s policy prohibits federal fudning for research using any human embryonic stem-cell except those established before August 2001.The issue is seen as religious moral issue dealing with human life by the Catholic Church and other religions As Dr. Okie’s editorial comment points out: "The Castle–DeGette bill, passed by Congress last summer, would have allowed the National Institutes of Health (NIH) to fund research on additional stem-cell lines developed from excess embryos donated by couples who had undergone in vitro fertilization (IVF) procedures. Although the bill passed, there were insufficient votes to override the President’s veto, which Bush announced at a press conference surrounded by children who had been "adopted" as embryos. "This bill would support the taking of innocent human life in the hope of finding medical benefits for others," Bush said. "It crosses a moral boundary that our decent society needs to respect."
