I remain optimistic that the Senate leadership will stand by the pledge made last year to move an embryonic stem cell bill forward. Until this vote happens, however, I will continue to lobby for this legislation and the ground-breaking science it represents. The longer a vote is delayed, the longer full potential of embryonic stem cells will be delayed. While Congress fails to act, people will continue to suffer and the United States will continue to fall behind and lose scientists to other nations in this cutting edge arena.
