The Obama administration released final regulations governing stem cell research on Monday. The New York Times reports that the rules will allow many older stem cell lines to be eligible for federally financed research. "The changes came in response to criticism from scientists that the rules that the administration proposed in April - requiring that donors of fertilized eggs sign extensive consent forms - would have made even some of the stem cell lines approved by the Bush administration ineligible for further money," the Times reports. "Scientists using stem cell lines created before Tuesday may seek review by a group of the Advisory Committee to the Director."
Dr. Raynard S. Kington, acting director of NIH, said that older stem cell lines will be approved if they were created under conditions that met the spirit of the new rules. The New York Times notes: "The crucial test is whether the embryos used to create the stem cell lines were created for reproductive purposes, and whether donors freely consented for their use in research procedures. ... Some older stem cell lines will be eligible, but [Kington] refused to speculate which of the older lines would be approved. ... The rules still forbid financing of research using stem cell lines from embryos created solely for research. With more than $10 billion in stimulus money, health institute officials have been eager to expand stem cell research. Just 21 stem cell lines have been eligible for federal financing under the old rules. But researchers using private money have created more than 700 stem cell lines" (Harris, 7/6).
NPR reports: "Scientists say the new rules will give them a lot more freedom to do research that could one day lead to better treatments for injuries and disease." It notes: "Eight years ago, President George W. Bush came up with a policy that allowed federal dollars to pay for some stem cell research - but only using about 20 stem cell lines that had existed before August 2001. In the years since, says Dr. Arnold Kriegstein, scientists have learned to make much better stem cell lines. But those didn't meet approval for federal funds." But what will not be allowed is therapeutic cloning, which is a "controversial practice in which scientists obtain stem cells by cloning a human embryo. But scientists now think they may be able to one day use skin cells - not embryonic stem cells - to create cloned human tissue or even a complete human organ" (Shapiro, 7/7).
"President Obama lifted restrictions on the field in March, but left it to the National Institutes of Health to decide what stem cell research was ethically appropriate: only science that uses cells culled from leftover fertility clinic embryos -- ones that otherwise would be thrown away, the agency made clear in draft guidelines," the Los Angeles Times reports. "The issue: Trying to harness embryonic stem cells -- master cells that can morph into any cell of the body -- to create better treatments, maybe even cures, for such ailments as diabetes, Parkinson's and spinal cord injury. Culling those stem cells destroys a days-old embryo, which many strongly oppose on moral grounds. Once created, those cells can propagate indefinitely in lab dishes" (7/7).

Visitor Opinions In Chronological Order (2)
ADULT Stem Cells
posted by Kate on 15 Jul 2009 at 6:16 pmIf Pres. Obama had done a little investigation or research he would have found out that Adult Stem Cells (or autologous) have already either cured or put into remission over 700 diseases, including heart disease, certain cancers, diabetes, sycle cell anemia and many others. Embryonic???? So far, only brain tumors have come from having embryonic stem cells used.
(Autologous is one's own stem cells, a relative's, or from cord blood). Case Closed!
Recent Research On Oligodendrocytes And Myelin Repair
posted by Laura on 16 Jul 2009 at 9:06 amThere are two recent findings on the function of oliogodendrocytes and their function in myelin repair that I found of interest to me.
Salk researchers reprogram adult stem cells in their natural environment
Published: Monday, June 30, 2008 - 08:35 in Biology & Nature
"We have known that the birth and death of adult stem cells in the brain could be influenced be experience, but we were surprised that a single gene could change the fate of stem cells in the brain," says the study's lead author, Fred H. Gage, Ph.D., a professor in the Laboratory for Genetics and the Vi and John Adler Chair for Research on Age-Related Neurodegenerative Diseases.
"It was quite surprising that stem cells in the adult brain maintain their fate plasticity and that a single gene was enough to reprogram these cells," says Jessberger; first author Sebastian Jessberger, M.D., formerly a post-doctoral researcher in Gage's lab and now an assistant professor at the Institute of Cell Biology at the Swiss Federal Institute of Technology in Zurich. "We can now potentially tailor the fate of stem cells to treat certain conditions such as multiple sclerosis."
In patients with multiple sclerosis, the immune system attacks oligodendrocytes, which leads to the thinning of the myelin layer affecting the neurons' ability to efficiently conduct electrical signals. Being able to direct neural stem cells to differentiate into oligodendrocytes may alleviate the symptoms.”
Then this year HHMI came out and said:

MULTIPLE Sclerosis: A New Theory for Why Repair of the Brain’s Wiring Fails
Bottom line in this research:
“Although scientists had previously belied that PVL (periventricular leukomalacia) resulted when oligodendrocytes were killed off by stress or toxic injury, Rowitch and colleagues at Children’s Hospital in Boston recently found that, as in the MS study , oligodendrocytes precursors had been recruited to the site of white matter lesions and stood poised to repair the damage, but for some reason did not proceed.”
So if these research folks could get together along with stem cell research, maybe we could get some where!
