News from New York is that scientists have found a way to produce the equivalent of embyonic stem cells, using adult tissue. So far, the experiment is working with mice, but there's hope it could soon extend to human cells.
Currently, embyonic stem cells, with their almost limitless potential, are the only way scientists have to "grow" new cells for adult sufferers from various conditions including paralysis, diabetets or Parkinson's disease.
The only drawback is that they need to harvested from embryos, which raise all kinds of legal and ethical implications.
The new process, demonstrated yesterday, makes ordinary cells act like stem cells and so eliminate the need to cultivate a destroy embryos.
There's still a long way to go before the procedure can be used on humans, scientists have cautioned, and current lines of research must be simultaneoulsy continued.
