The most widely known source of stem cells is human/animal embryos, prompting controversy over stem cell research based on bioethics and the view that life begins at conception. It is now known that stem cells can also be obtained from placenta and amniotic fluids, and pluripotent cells can be derived from adult cells of the skin, blood and other tissues. Research on the use of stem cells from non-embryonic sources has received more attention in recent years as scientists in some countries, particularly the US, are forced to search for publicly accepted, ethical alternatives."
