More patient advocacy groups, universities and scientific societies are joining the call to remove US administration restrictions on stem cell research. This latest initiative was organized by the Coalition for the Advancement of Medical Research: you can read the full statement supported by 142 groups at their website. As I note at Fight Aging!, however, changing restrictions on federal funding doesn't address the bigger problem of legislative threats to therapeutic cloning. These threats are scaring away the vast potential of private funding for both adult and embryonic stem cell research. Therapeutic cloning is a vital technology, and banning it will block the most promising near term advances in regenerative medicine.
