Pardon us for raining on this parade of jubilation. A “milestone” the research of groups in Japan and Wisconsin may be, but their method does not yet negate the need for controversial research on embryonic stem cells. Scientists and supporters of stem cell research should not allow conservatives to declare victory and should persevere in their fight to eliminate restrictions on embryonic stem cell research...
...method the researchers in Japan and Wisconsin used to arrive at stem cells involves transferring four genes into the genome of a mature cell through virus. These four genes produce factors that “reprogram” the mature cell’s genome to a stem-like state. No viable embryo, therefore, is either created or destroyed—which is the main qualm of conservative opponents of the research...
...House Democrats reject such arguments. Bush's announcement in September that he was beginning a drawdown was "a study in calculated public deception," Rep. David Obey, the Wisconsin Democrat who heads the House Appropriations Committee, said last week. The pullout of 30,000 troops by next summer will still leave about 140,000 troops in Iraq, the same size force that was there before the 30,000-strong "surge" began earlier this year. "He made clear in that speech that as far as he's concerned," Obey said, "we're going to be there for the next decade...
...into acting like an embryonic stem cell - capable of dividing, developing and maturing into any of the body's more than 200 different cell types. And he wasn't alone: on the same day that he published his milestone in the journal Cell, James Thomson, a pioneering University of Wisconsin molecular biologist, reported similar success in Science...
...answer is a resounding yes, as evidenced by two groundbreaking papers published on Tuesday. In the journal Cell, Shinya Yamanaka of Kyoto University reports success in turning back the clock on cheek cells from a middle-aged woman, while James Thomson of University of Wisconsin, the first to isolate human embryonic stem cells, achieved the same feat with foreskin cells from a newborn baby. The achievements completely reset the boundaries of the stem cell debate, because both groups generated cells that looked and acted like embryonic stem cells, but without the need for eggs, embryos or ethical quandaries about where...
