This is for the fact that scientists can only find and use them from embryos that are a few days old (Mayo). These are the cells that have more potential to help and be used in medicines. Saxena mentions that the reason that embryotic stem cells are so useful is for the fact that these are the cells that can divide and change into a different type of cell (225). A big problem is that these cells are hard to come by for the fact that since they are basically a baby in the making, they were and are protected by many different policies. The only way that scientists are able to obtain stem cells is when they “are derived from embryos that develop from eggs that have been fertilized in- vitro clinic and then donated for research purposes with informed consent of the donors.” (Saxena, 225) In vitro mean to be made in a test tube or outside of the body (Webster, 659). Adult stem cells much easier to obtain and are currently the most used types of cells for stem cell therapy. These cells are able to be “isolated” from areas of the body such as the bone marrow, umbilical cords, the placenta, and even certain body fats. Although these stem cells are still very useful, not all of them are able to differential like the embryotic stem cells. One of the few adult stem cells that are somewhat able to change are the bone marrow stem cells (Mayo,
