Embryonic stem cells research is often times confused with human or reproductive cloning. Cloning is different in that the cells are copied so that their genetic material, or DNA, matches exactly. Embryonic stem cell research utilizes therapeutic cloning, or somatic cell nuclear transfer, to copy cells with the goal of making stem cells to treat and cure serious diseases and injuries. Using SCNT, scientists can produce embryonic stem cells without using sperm to fertilize an egg
