In the human body, stem cells create new blood cells. What makes them different from other types of cells in the body, however, is that stem cells are capable of developing into various different types of cells. Because stem cells occur in the earliest stages of development it is possible for them to become cells such as those found in organs or nearly any part of the body. Though there has been a lot of controversy surrounding stem cell research, it allows doctors and scientists to find and develop new ways of using the stem cells to repair body parts that have become damaged as a result of illness of injury. Though some people oppose the practice, there are numerous benefits of stem cell research.

Many people oppose stem cell research because the cells are often obtained from embryos. They often come from this source because in the embryo stem cells are in their absolute earliest state, and at this time they have the greatest ability to be used for a number of purposes because they have the ability to develop into many cell types. The primary benefit of stem cell research is that such study has the potential to greatly advance the medical field. In fact, research has already shown that stem cells can be used in treating various medical conditions that are currently incurable including Multiple Sclerosis, Parkinson's, and Alzheimer's. Further research could allow scientists to find ways to cure or stop the progression of such diseases rather than just treating the symptoms. It may be possible to use stem cells to cure or lessen the effects of nearly any ailment or health problem. Overall, stem cells could eventually be used to greatly improve the lives of those who are ill.

In addition to providing life saving benefits, stem cell research may also lead to medical advances in the field of cosmetic surgery. In fact, a "stem cell facelift" is now possible. In this procedure, stem cells are grafted on to the face in a procedure that is simpler, safer, and more effective than a traditional facelift. Because the procedure is so much simpler, it also comes with a lower price tag. While this benefit may not seem as substantial as the possibility of curing cancer or other terminal illnesses, it does offer hope that it may be possible to use stem cells to treat nearly any problem.
