NIH issues new stem cell research guidelines
By Jordan Lite in 60-Second Science Blog

 The National Institutes of Health (NIH) today released draft guidelines 
that permit federal funding for research on stem cells from human embryos 
set to be discarded by fertility clinics.

Under the new regs, the agency would fund studies on embryos created in test 
tubes - but no longer needed - for reproductive purposes, adult stem cells 
and induced pluripotent stem cells (skin or other adult cells that are 
nudged back into their pluripotent state, when they have the potential to 
become any cell type). Fertility patients would have to consent to their 
leftover embryos being donated for research.

The rules bar funding for research on embryos created expressly for 
stem-cell studies; ditto for studies involving embryos derived from somatic 
cell nuclear transfer (replacing the nucleus of an unfertilized egg with 
genetic material from another body cell and stimulating it to divide) or 
parthenogenesis (reproduction without fertilization).

"This is an incredible opportunity for the scientific community and the 
health of the people [who may benefit] by what we learn from this additional 
science," Raynard Kington, NIH's acting director, said during a 
teleconference with reporters today. Scientists believe that embryonic stem 
cells, which have the ability to morph into any type of tissue in the human 
body, could one day be used to treat conditions such as diabetes and 
Parkinson's disease.

Former President George W. Bush banned federally funded research on 
embryonic stem-cell lines created after Aug. 9, 2001. On March 9, President 
Obama lifted the ban and gave the NIH 120 days to craft guidelines governing 
such research. Scientists complained that Bush's ban limited research to 
about two dozen stem-cell lines of varying quality. But there may now be 
some 700 embyronic stem-cell lines that would qualify for federal funding 
under the new guidelines, Kington said. (Congress passed legislation twice 
calling for the limit to be lifted on stem cell research, but Bush vetoed 
both bills.)

The proposed new regs disappointed some who said the prohibition on funding 
of embryos created specifically for research could hamper the creation of 
treatments such as organ tissue genetically matched to prospective 
transplant recipients, the New York Times notes.

"The proposed guidelines limit some very promising avenues of current 
research and limit the genetic diversity of the stem cell lines that will be 
eligible for federal funding," Susan Solomon, CEO of the nonprofit New York 
Stem Cell Foundation, said in a statement. "This is a very young field, with 
the promise to combat the most deadly diseases of our time. Scientists need 
to be able to deploy a full arsenal, one that encompasses what may be 
possible in the future."
