Nuclear transfer technology, which allows you to create stem cells that are genetically identical to a particular patient, may be ... necessary in order to get the full value out of embryonic stem cells. This is the matter of taking the nucleus from a skin cell, putting it in a hollowed-out egg cell in a dish and growing it to the point where you can take stem cells out of it. It never enters a womb. Sperm and egg never meet. There's no pregnancy and yet the opponents of this research continue to cast this in terms of these are little tiny lives. In fact, these are specks smaller than a grain of sand in which we can derive stem cells that could have vast scientific and medical benefit.
