Bill Introduced to Codify U.S. Stem Cell Rules

Congressional supporters of stem cell research have re-introduced legislation to codify President Barack Obama's 2009 executive order lifting restrictions on the number of human embryonic stem cell lines available to federally funded researchers.

Today's announcement was timed to the 1-year anniversary of the order, which lifted the Bush-era ban against the use of lines derived after 9 August 2001. The Stem Cell Research Advancement Act aims to "ensure a lasting ethical framework" for such research. It is sponsored by Representatives Diana DeGette (D-CO) and Michael Castle (R-DE) and was vetoed twice by former President George W. Bush.
