Scientists announced this week that they retrieved stem cells from monkey embryos which developed from an egg but no sperm. Last week, another research team reported the discovery of a new class of adult stem cells that can turn into many different types of cells. Do these findings represent viable therapeutic alternatives to stem cells derived from normal human embryos? In this hour, we'll discuss the latest advances in stem cell research and the importance of human embryonic stem cell research.
