A microscopic view shows smooth muscle cells derived from human embryonic stem cells showing the nuclei (blue) and proteins of the cytoskeleton (green) in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009. These cells could one day be used to replace smooth muscle of the blood vessels, bladder, intestines or uterus.(Xinhua/Reuters Photo)
A microsopic view shows human embryonic stem cells in various stages of differentiation into liver cells in this photo taken at Stanford University and released by the California Institute for Regenerative Medicine, March 9, 2009. Green cells are expressing a fetal liver cell protein called alpha-fetoprotein. Red cells are expressing albumin, a marker of more mature liver cells. Liver cells could one day be used to screen drugs for toxic side effects or for transplantation. (Xinhua/Reuters Photo

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.
