Cells produced with SCNT, or iPSCs could eventually be used in stem cell therapy ,  or to create organs to be used in transplantation, known as regenerative medicine . Stem cell therapy is the use of stem cells to treat or prevent a disease or condition. Bone marrow transplantation is a widely used form of stem cell therapy.  No other forms of stem cell therapy are in clinical use at this time. Research is underway to potentially use stem cell therapy to treat heart disease , diabetes , and spinal cord injuries .   Regenerative medicine is not in clinical practice, but is heavily researched for its potential uses. This type of medicine would allow for autologous transplantation, thus removing the risk of organ transplant rejection by the recipient.  For instance, a person with liver disease could potentially have a new liver grown using their same genetic material and transplanted to remove the damaged liver.  In current research, human pluripotent stem cells have been promised as a reliable source for generating human neurons, showing the potential for regenerative medicine in brain and neural injuries. 
Animal research has played a vital role in virtually every major medical advance of the last century -- for both human and animal health. From antibiotics to blood transfusions, from dialysis to organ-transplantation, from vaccinations to chemotherapy, bypass surgery and joint replacement, practically every present-day protocol for the prevention, treatment, cure and control of disease, pain and suffering is based on knowledge attained through research with animals.
