    President Obama is expected to reverse Bush administration blocks on federal funding of stem cell research.

    WASHINGTON — Eight years of frustration are close to an end for scientists seeking ways to use embryonic stem cells to combat illness and injury.

    On Monday, President Barack Obama plans to reverse limits imposed by President George W. Bush on using federal money for research with embryonic stem cells.

    The long-promised move will allow a rush of research aimed at one day better treating, if not curing, ailments from diabetes to paralysis — research that crosses partisan lines, backed by such notables as former first lady Nancy Reagan and the late actor Christopher Reeve.

    But it stirs intense controversy over whether government crosses a moral line with such research, and opponents promptly denounced the move.

    Obama will hold an event at the White House to announce the move, a senior administration official said Friday. The official spoke on condition of anonymity because the policy had not yet been publicly announced.

    Embryonic stem cells are master cells that can morph into any cell of the body. Scientists hope to harness them so they can create replacement tissues to treat a variety of diseases — such as new insulin-producing cells for diabetics, cells that could help those with Parkinson's disease or maybe even Alzheimer's, or new nerve connections to restore movement after spinal injury.

    "I feel vindicated after eight years of struggle, and I know it's going to energize my research team," said Dr. George Daley of the Harvard Stem Cell Institute and Children's Hospital of Boston, a leading stem cell researcher.

    But the research is controversial because days-old embryos must be destroyed to obtain the cells, and some conservatives believe that destroys a life. The embryos typically are culled from fertility-clinic leftovers otherwise destined to be thrown away.

    Under Bush, taxpayer money for that research was limited to a small number of stem cell lines that were created before Aug. 9, 2001, lines that in many cases had some drawbacks that limited their potential usability.

    But hundreds more of such lines — groups of cells that can continue to propagate in lab dishes — have been created since then, ones that scientists say are healthier, better suited to creating treatments for people rather than doing basic laboratory science.

    Work didn't stop. Indeed, it advanced enough that this summer, the private Geron Corp. will begin the world's first study of a treatment using human embryonic stem cells, in people who recently suffered a spinal cord injury.

    Nor does Obama's change fund creation of new lines. But it means that scientists who until now have had to rely on private donations to work with these newer stem cell lines can apply for government money for the research, just like they do for studies of gene therapy or other treatment approaches.

    The aim of the policy is to restore "scientific integrity" to the process, the administration official said.

    "America's biomedical research enterprise experienced steady decline over the past eight years, with shrinking budgets and policies that elevated ideology over science. This slowed the pace of discovery and the search for cures," said Sean Morrison, director of the University of Michigan's Center for Stem Cell Biology.

    Critics immediately denounced the move.

    "Taxpayers should not have to foot the bill for experiments that require the destruction of human life," said Tony Perkins of the conservative Family Research Council. "President Obama's policy change is especially troubling given the significant adult stem cell advances that are being used to treat patients now without harming or destroying human embryos."

    Indeed, there are different types of stem cells: So-called adult stem cells that produce a specific type of tissue; younger stem cells found floating in amniotic fluid or the placenta. Scientists even have learned to reprogram certain cells to behave like stem cells.

    But even researchers who work with varying types consider embryonic stem cells the most flexible and thus most promising form — and say that science, not politics, should ultimately judge.

    "Science works best and patients are served best by having all the tools at our disposal," Daley said.

    Obama made it clear during the campaign he would overturn Bush's directive.

    During the campaign, Obama said, "I strongly support expanding research on stem cells. I believe that the restrictions that President Bush has placed on funding of human embryonic stem cell research have handcuffed our scientists and hindered our ability to compete with other nations."

    He said he would lift Bush's ban and "ensure that all research on stem cells is conducted ethically and with rigorous oversight."

    "Patients and people who've been patient advocates are going to be really happy," said Amy Comstock Rick of the Coalition for the Advancement of Medical Research.
