If you had a grandparent with Alzheimer's or a best friend who was paralyzed from the waist down, wouldn't you want them to be magically healed? Well, many scientists believe they found the magical cure. Stem cell research is a controversial issue in America. Stem cells are a primitive cell that can multiply and conform to be any cells. Unfortunately, the best source for stem cells is human fetal tissues. To extract the stem cells, you will in turn, kill the embryo. This has been the source of dispute since the discovery of stem cells as a cure for disease and injuries.
The President has signed a bill that research on stem cells may continue, yet they can only uses the embryos that they have in the labs. This is the only option he had that appeased both sides of the issue. Stem Cell research has come a long way in five years yet still has a long way to go. So far we know that when we take out these certain cells and cultivate it form 220 types of cells. So far scientists have been able to heal a paralyzed rat using stem cells. That's a huge advancement and on top of that they are working on healing many cancers with stem cells. Even though there is nothing controversial about what stem cells do, the method of obtaining the cells are the real problem.
Many people in America believe the destroying of an embryo murder. Whether being abortion or for stem cell research, they believe it is morally wrong. That is a personal decision. There is also a concern where cloning is concerned. Both of these are options for obtaining stem cells. But rather from removing an embryo from an actual woman, they are from clinic where the eggs and sperm are donated. They are also only 3 to 4 days old. These embryos are either created especially for research or eggs that will not be used. Rather than throw them out, they uses them for science. There is also controversy about cloning embryos. Scientists take a fertilized egg and clone it so that they have more eggs to extract the cells from.
