Government Funding Of Embryonic Stem Cell Research Can Continue For Now

 According to the article below, An appeals court ruled Tuesday that government funding of embryonic stem cell research can continue for now. Researchers hope one day to use stem cells in ways that cure spinal cord injuries, Parkinson's disease and other ailments. Opponents say the research is a form of abortion because human embryos must be destroyed to obtain the stem cells. There really are two sides to this issue. the court will decide.

 Court OKs US-funded stem cell research for now
Yahoo! News:

WASHINGTON – An appeals court ruled Tuesday that government funding of embryonic stem cell research can continue for now.

The U.S. Court of Appeals in Washington granted the Obama administration's request to allow the funding from the National Institutes of Health while it appeals a judge's order blocking the research.

The administration had argued that stopping the research while the case proceeds would irreparably harm scientific progress toward potentially lifesaving medical treatment.

U.S. District Judge Royce Lamberth had blocked President Barack Obama's research funding guidelines because he said it's likely they violate the law against federal funding of embryo destruction.

A three-judge panel of the appeals court issued an unusually quick decision, a day after hearing arguments over whether the funding could continue while it considers the case. The court also said it would expedite the case.

Researchers hope one day to use stem cells in ways that cure spinal cord injuries, Parkinson's disease and other ailments. Opponents say the research is a form of abortion because human embryos must be destroyed to obtain the stem cells.

A 1996 law prohibits the use of taxpayer dollars in work that harms an embryo, so batches have been culled using private money. But those batches can reproduce in lab dishes indefinitely, and Obama administration issued rules permitting taxpayer dollars to be used in work with the already created batches.

The administration thus expanded the number of stem cell lines created with private money that federally funded scientists could research, up from the 21 that President George W. Bush had allowed to 75 so far.

"President Obama made expansion of stem cell research and the pursuit of groundbreaking treatments and cures a top priority when he took office," White House spokesman Robert Gibbs said in a statement after the ruling. "We're heartened that the court will allow NIH and their grantees to continue moving forward while the appeal is resolved.

New Adult Stem Cells Could Speed Progress in Regenerative Medicine

According to the following article, researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases. This is a really exciting development, because it eliminates the controversy about embryonic stem cells.

Researchers Engineer Adult Stem Cells That Do Not Age, Overcoming a Major Barrier to Progress in Regenerative Medicine:

Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune disorders and neurodegenerative diseases.

UB scientists created the new cell lines – named "MSC Universal" – by genetically altering mesenchymal stem cells, which are found in bone marrow and can differentiate into cell types including bone, cartilage, muscle, fat, and beta-pancreatic islet cells.

Lee says his research team has generated two lines of MSC-Universal cells: a human line and a porcine line. Using the engineering technique he and colleagues developed, scientists can generate an MSC-Universal line from any donor sample of mesenchymal stem cells, he says.

"I imagine that if these cells become routinely used in the future, one can generate a line from each ethnic group for each gender for people to choose from," Lee says.

The researchers say the breakthrough overcomes a frustrating barrier to progress in the field of regenerative medicine: The difficulty of growing adult stem cells for clinical applications.

Because mesenchymal stem cells have a limited life span in laboratory cultures, scientists and doctors who use the cells in research and treatments must continuously obtain fresh samples from bone marrow donors, a process both expensive and time-consuming. In addition, mesenchymal stem cells from different donors can vary in performance.

The cells that UB researchers modified show no signs of aging in culture, but otherwise appear to function as regular mesenchymal stem cells do – including by conferring therapeutic benefits in an animal study of heart disease. Despite their propensity to proliferate in the laboratory, MSC-Universal cells did not form tumors in animal testing.
