Erika Check Hayden Heather Melichar (left) and Ou Li at the University of California, Berkeley, can now use the federally funded equipment in their main lab to do embryonic stem-cell research. P. Skorpinski Scientists and research advocates worldwide are celebrating the removal of rules limiting research on human embryonic stem cells in the United States, which they say have restricted the field's progress for seven and a half years. The National Institutes of Health (NIH) in Bethesda, Maryland, is now working out policies that will allow researchers to apply for grant money from the agency to study some of the hundreds of cell lines created since 9 August 2001, when President George W. Bush limited federal funding to research on lines in existence at that time. Some scientists are already proposing to use the new lines in applications for $200 million in NIH 'Challenge' grants, which will be funded by the economic stimulus package signed into law last month. Details of these grants were unveiled last week (see NIH website ). Estimates of the number of new lines range from 400 to 1,000. Unlike the 21 lines previously eligible for federal funding, many of the lines have been made from embryos that had genetic predispositions to specific diseases, or were derived using 'animal-free' preparations, and thus could be more relevant to laboratory research and preclinical studies.
