Abstract
One year after President George W. Bush announced that some 60 human embryonic stem cell lines were available, U.S. scientists have their hands on just four; practical and legal hurdles have kept most of the lines in the labs where they were derived. And because relatively few have been fully characterized, it's not clear that all of them are in fact bona fide stem cells.Keywords
