A human embryonic stem cell line derived at Stanford University is seen in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009. The line was derived under controlled conditions that could make the cells useful for transplantation. The nuclei in green are stained for a protein that is found only in embryonic stem cells while blue represents the DNA of the surrounding feeder cells. U.S. President Barack Obama lifted restrictions on federal funding of human embryonic stem cell research, angering abortion opponents but cheering those who believe the study could produce treatments for many diseases.(Xinhua/Reuters Photo) |
