In an experiment that will further complicate the debate on the ethics of stem cell research, scientists have taken stem cells from a monkey "embryo" coaxed to develop from an egg that was not fertilized by sperm. In a report in Science magazine this week, they report that these stem cells show the same characteristics as human embryonic stem cells. They were induced to develop into neural cells, spontaneously beating heart-like cells, smooth muscle cells, fat cells and others. NPR's Joe Palca reports.
