Embryonic stem cells. Stem cell programs

The availability of human embryonic stem cell lines provides an important tool for scientists to explore the fundamental mechanisms that regulate differentiation into specific cell types. When more is known about the mechanisms that govern these processes, human embryonic stem cells may be clinically useful in generating cell types that have been damaged or depleted by a variety of human diseases. The NIH is actively pursuing a variety of initiatives to promote this developing research field, while continuing and expanding its long-standing investment in adult stem cells and research.     

Stem cell research. U.K. backs use of embryos, sets vote

The U.K. government last week endorsed a report that advocates tapping embryos for their stem cells, unspecialized cells that may ultimately serve as seed material for growing tissues to treat diseases. It also opens the door to cloning human embryos for research--an activity that has triggered sharp debate. Legislation implementing the recommendations will go to Parliament for a vote this fall.
