...many as 50 Republicans could join Democrats in favor of it. While the legislation presents Republican moderates a rare opportunity for victory on Capitol Hill, it has also attracted the interest and support of some conservatives who say they discern a growing pro- life case for what embryonic-stem-cell research has to offer...
That's an excruciating prospect for the White House, made all the more so by the fact that a rejection of the stem-cell legislation would be Bush's first veto ever. Opponents of embryonic-stem-cell research say they have received private assurances from the White House that the President will stay true to his word, and they are working to get enough votes on their side so that the veto cannot be overturned. Meanwhile, White House aides are huddling with some congressional leaders to come up with an alternative measure of some kind that, in the words...
...President's stance is one of the few markers on the field of embryonic- stem-cell research that hasn't moved over the past four years. When Bush announced his Executive Order limiting federal funding to studies on existing stem-cell lines, he declared that private research had produced more than 60 genetically diverse lines that would be eligible. Researchers now say the number is more like 22, and even those are contaminated with mouse DNA, making them ill-suited for use on humans. Meanwhile, research is moving ahead without Washington's sanction--not only in places like Britain...
...brightest minds, now find themselves at a disadvantage, and so many are looking elsewhere. G.O.P. Congressman Mark Kirk, a leading backer of the bill, says universities and research institutions in his Chicago-area district are complaining that some of their top talent is leaving for places that offer stem-cell-research programs. At the same time, the diffusion of this work across the nation also raises ethical questions, as each state gets to set its own standards. "One of the fears here is that you are going to have a potpourri of different approaches to this--some of them stretches...
What excites scientists about the unspecialized stem cells is their potential to develop into any type of tissue, from bone and muscle to skin and blood and nerve. Although there are several kinds of stem cells--including ones found in adult bone marrow and umbilical-cord blood--the most versatile, researchers say, are the ones that come from embryos, because they haven't yet developed enough to specialize at all. Those are the ones that scientists believe hold the greatest potential for treatment of a wide range of diseases, as well as for repairing damaged nerves and organs...
