Scientists comparing the safety and pluripotency of adult and embryonic stem cells now have a sophisticated new tool at their disposal, according to an article published today in Cell. They've developed an assay that permits a comparatively fast and accurate determination of how the stem cells will behave over time. As I reported in my last post, the debate over the efficacy and safety of adult and embryonic stem cells continues, and this is an important new tool in stem cell scientists' tool kit. As always, ethicists should follow these developments closely.
