The Debate Over Stem Cells

Good Essays
What would our world be like today without cancer, heart disease, or even diabetes? These are just a few examples of the diseases that stem cells can treat. A stem cell is a cell that has the potential to mutate into many different types of cells in the body. Ever since stem cells were discovered, they have gained popularity and started to spark interest in scientists all across the world. Today there is a vigorous battle on the ethics, legalization, and experimentation of stem cells. Although stem cells are still being highly debated, they can open new doors in the scientific world and change medical treatment that we receive in the future. As stated above, stem cells are cells that may mutate into many different types of cells. These types of cells tend to “divide into daughter cells and keep regenerating under good conditions” (Green 7). However, they will not regenerate if there is tissue rejection. If the tissue rejects the new stem cells, the immune system will kill them off and the procedure will be ineffective. This can be prevented by using the patient’s own stem cells, embryonic stem cells, engineering the cells correctly, or replacing the patient’s immune system with immune cells from the donor. Furthermore, stem cells can be useful for treating many diseases because of their wide variety of use. They are taken from a healthy part of the body, such as an organ or bone, and then replaced into a patient’s damaged body part. The healthy cells
