Washington, DC (LifeNews.com) -- Pro-life organizations say that recent news from Wake Forest scientists about the potential for amniotic stem cells should give members of Congress pause as they consider whether to approve legislation to force taxpayers to fund embryonic stem cell research.

The researchers have been able to successfully manipulate stem cells found in the amniotic fluid of a pregnant woman that have many properties of embryonic stem cells.

They have been able to grow the cells into various tissue types -- the big benefit often cited for embryonic cells -- but without the tumors that accompany the injected of embryonic cells or the destruction of human life needed to obtain them.

As a result, one pro-life advocate says he hopes Congress will pass on spending tax dollars on the embryonic stem cell research.

“This new science has been able to isolate every type of stem cell needed for therapy and healing medicine without the moral concern for loss of innocent life," Operation Rescue president Troy Newman said.

Rev. Patrick Mahoney of the Christian Defense Coalition agreed and said “Based upon this stunning new revelation, we strongly recommend that Speaker Nancy Pelosi refrain from moving forward in her plans to fund the highly controversial embryonic stem cell research."

Mahoney and Newman are drafting a letter to Pelosi along with the pro-life National Clergy Council, and Generation Life, an organization for pro-life teens and young adults, urging her to hold a vote on the bill.

Meanwhile, Tony Perkins, the president of the Family Research Council, is urging pro-life Americans to call their members of Congress and urge strong opposition to the embryonic stem cell research legislation.

"Last July, President Bush vetoed the same bill and the House upheld the veto. However, H.R. 3 would overturn the Bush policy and create a direct incentive to create and kill human embryos for research with your taxes," he wrote in a letter to the group's supporters.

"Please contact your Representative and let him or her know that you strongly oppose H.R. 3," Perkins added.

"We should not force U.S. taxpayers to fund research that requires the destruction of embryos," he said.
