This research is significant because it suggests that it will be possible to create mouse 'models' of human brain tissue, enabling scientists to try out both stem cell interventions and other potential cures on living human brain cells without having to use humans in the process.
A stem cell trial like this without full review should just never, ever happen. The University of Pittsburgh should take the lead in the nation to ensure that this option is never provided, since they are the ones that did it wrong.
Only a properly funded US stem cell research program will guarantee oversight and the protection of all involved.
Ethics can get forgotten as other nations and private companies race to fill the void left by the president's reluctance to fund stem cell research. Only a properly funded U.S. stem cell research program will guarantee oversight and the protection of all involved.
