The House is expected to vote Tuesday on legislation that would loosen restrictions on federal funding for embryonic stem cell research. President Bush says he'll veto the bill. The bill's supporters say some embryos should be donated for research. But opponents, who believe life begins at conception, are offended by the idea.
JENNIFER LUDDEN, host: From NPR News, this is ALL THINGS CONSIDERED.  I'm Jennifer Ludden.</s>JENNIFER LUDDEN, host: While the US Senate braces for a showdown over the filibuster rules, the      House of Representatives is wrangling over stem cell research.  The House      is expected to vote Tuesday on legislation that would loosen restrictions      on federal funding for embryonic stem cell research.  President Bush says      he will veto the bill, but NPR's Nancy Marshall-Genzer reports, the      debate goes on and is not limited to Congress.</s>NANCY MARSHALL-GENZER reporting: In 2001, President Bush banned federal funding for research using new      embryonic stem cell lines.  The House bill would change that, allowing      government-funded researchers to work with stem cells drawn from embryos      left over from fertility treatments.  The bill's supporters say instead      of being discarded, the excess embryos could be donated for research.      But opponents, who believe life begins at conception, are offended by the      idea.  The debate spilled into the networks' Sunday talk shows today.</s>Unidentified Reporter: Time now for The List.  And we continue our      earlier discussions of stem cells with two passionate women who have a      very personal stake in the debate.</s>MARSHALL-GENZER: Those `passionate women' appearing on ABC's "This Week"      were Christopher Reeve's wife Dana and evangelist Billy Graham's      daughter, Ann Graham Lotz.  The families of both women have been affected      by disability and disease.  Graham Lotz spoke first followed by Reeve.</s>Ms. ANN GRAHAM LOTZ: I have a father who has Parkinson's disease.  I      have a son who has cancer.  I have a mother who has degenerative      arthritis.  I have a husband who has diabetes.  But I would not want any      one of my family members to benefit from the willful destruction of      another human life.</s>Mrs. DANA REEVE: There is not a disorder you can name that wouldn't      benefit from stem cell research:  eyes, heart, lungs, every part of the      body.  The stem cell discovery is going to be the most prominent      discovery, I think, in our lifetime for sure.</s>MARSHALL-GENZER: The debate that divides Reeve and Graham Lotz also      divides Republicans.  Conservative Senator Orrin Hatch of Utah has gone      so far as to co-sponsor legislation that would make it easier to obtain      new stem cell lines.  Some House Republicans have come up with a      compromise.  They're backing a measure supporting research on stem cells      culled from umbilical cord blood.  But many scientists say those types of      stem cells would be of little value.  David Shaywitz, a stem cell      researcher at Harvard, says the umbilical cord stem cells don't have the      flexibility of embryonic stem cells.</s>Mr. DAVID SHAYWITZ (Harvard): All stem cells are not created equal.      Embryonic stem cells have the ability to specialize into any cell type in      the body.  Adult blood stem cells and embryonic cord blood stem cells      only have the ability to become other blood cells.</s>MARSHALL-GENZER: As Congress wrestles with the ethics of stem cell      research, other nations have generously funded it.  Last week South      Korean scientists announced they'd come up with an improved method of      generating embryonic stem cells.  They used human eggs and DNA from      people suffering from disease or disability.  The scientists hope they      can eventually use the stem cells to treat those patients.</s>MARSHALL-GENZER: Nancy Marshall-Genzer, NPR News, Washington.
