WASHINGTON (AP) - A procedure that encourages an egg to begin embryo development without being fertilized could suggest a new way to produce stem cells, at least for certain patients.
Researchers were able to get stem cells using unfertilized mouse eggs, they report in Thursday's online issue of the journal Science.
They are now turning their attention to eggs from people, but several problems remain to be worked out.
Stem cells can develop into many different types of tissue, making them basic building blocks of the developing body. Finding ways to produce them has become a major research focus, as these cells hold the promise to one day help repair damage from nerve-destroying illnesses such as Lou Gehrig's disease, or from spinal cord injuries or other illnesses.
