While promoting some types of stem cell research he curtailed the form of research that involves destroying human embryos. The president made the announcement in his first television address to the nation to emphasize the significance of the decision. If we are to appreciate the importance of that announcement we need to understand what stem cell research involves and why it is important. \';H.-\T IS STEM CELL RES E,-\ RCH/ Stem cells are the basic building blocks for the cellular development of our bodies. There are three main distinctions that need to be made. A fertilized egg is considered to be "totipotent" because its cells have the total potential of developing into a human fetus. When these dividing cells form the blastocyst. its inner mass cells are "pluripotent" insofar as they can develop into almost any other cell type. When pluripotent cells further divide into particular cell functions (skin cells. blood cells. etc) they are "multipotent" because they can develop into most forms of that specific cell type (e.g. blood stem cells in the bone marrow).
