The advantages of embryonic stem cells is that they offer one cell source for multiple indications. They provide the potential for a wider variety of applications than do adult stem cells. Additionally, they theoretically have the possibility of being immuno-privileged, due to their highly undifferentiated state. A privileged immune status would remove one of the main barriers of stem cell therapies, as self rejection is one stem cell therapy’s main complications [17]. The idea that embryonic stem cells can be immune privilaged, must be viewed skeptically, however, as this theory has not yet been
