There are embryonic stem cells and adult stem cells. Embryonic are all brand new and don't know exactly what they will become yet. Adult stem cells are replacement cells for other cells of the body. So they are more inclined to become what they are supposed to replace. Embryonic stem cells are the favorite type of cells to use in stem cell research because they are more likely to become what scientists want them to be. And here in lies the controversy: is stem cell research ethical?
Many believe it is unethical because those embryos that are used could have developed into a living person. Then there are those who think stem cell research is a wonderful thing that can help cure diseases. People that have spinal cord injuries, diabetes, heart disease, alzheimers, and parkinsons would benefit from stem cell treatment.
Many of those who oppose stem cell research say that we should use umbelical cords which have stem cells or adult stem cells instead of embryonic stem cells. Many say, however, that these cells just aren't as good as embryonic cells because they are more capable of becoming whatever cell scientists tell it to be.
One activist for stem cell research was Christopher Reeve. He was injured in a horse riding accident and he was paralyzied from the neck down. He became a major activist for stem cell research. He passed away in 2004.
So the question is is stem cell research and treatment ethical? Is it better to use embryonic cells to help save those that are suffering from diseases? Or is it wrong to do so because those embryos have a chance at life? This issue is one that will be debated for years to come. What is your stance?
