Stem Cell

Human embryonic stem cells can live on indefinitely when carefully cultured under just the right conditions. The legal and legislative environments for these cell lines, however, has gotten a lot less hospitable in recent weeks.

After a federal judge placed an injunction on federal funding for all human embryonic stem cell (hESC) research in late August scientists and advocates faced rules that were far more stringent than those under the George W. Bush administration. A temporary lift of the injunction, issued September 9 by a federal appeals court, has done little to solidify the field’s future.
