He explained: "We are very close to this issue in our family; one of our daughters has used in-vitro procedures in an attempt to have additional children." While the attempt was unsuccessful, Bennett said her experience showed him "that all embryos are not created equal; some are healthy enough to have a chance of survival, and some are not."

That experience caused Bennett to conclude "that federally funded research on embryo stem cells should proceed, under careful ethical and procedural guidelines."

Reid, D-Nev., said embryonic stem cell research holds the promise of helping millions afflicted with diabetes, Alzheimer's disease and other illnesses. He urged an "up-or-down vote," meaning one with no amendments allowed.

Meanwhile, the Republican chief sponsor of the Senate bill, Sen. Arlen Specter of Pennsylvania, who is being treated for cancer, made a personal appeal for quick action.

"I look in the mirror every day, barely recognize myself," said Specter, whose hair has been lost to chemotherapy treatment. "And not to have the availability of the best of medical care is simply atrocious."

Specter said that if Senate Republican leader Bill Frist refuses to allow the bill a vote, "we are not without remedies," namely procedures by which senators can try to add the bill to other measures being considered on the floor.

The House approved legislation Tuesday on a vote of 238-194 — far less than the two-thirds support that would be needed to override a veto by the president.

"There's no chance it will become law," said Rep. Dave Weldon, R-Fla., one of numerous abortion foes to oppose the House measure. "I don't know why the Senate would bother taking it up."
