| Description | Embryonic stem cells can potentially revolutionize the way we treat disease, providing a source of tissue to replace or repair a huge variety of disorders. In the US, however, funding of stem cell research has been limited by policy decisions and, once those decisions were reversed, a court ruling. In the intervening years, researchers developed what appeared to be a promising alternative, a technique that could push any adult cell into a state that appeared to be indistinguishable from an embryonic one. Unfortunately, researchers have now looked a bit more closely at these induced pluripotent stem cells (iPSCs), and found that they are distinct from embryonic ones, in part because they retain the imprint of their former, mature state. |
