Embryonic stem cell research is one of the most promising, fascinating, and not to mention, controversial issue in science today. It has generated debate, protest, and most importantly, hope. Scientists have discovered that stem cells hold huge potential to treat countless diseases such as Alzheimer's, Parkinson's, arthritis, diabetes, and spinal cord damage. How does this all work? The answer lies in the miraculous embryonic stem cells. They are basically unspecialized cells that can be manipulated into any of the 220 types of human cells known (Q&A: Stem Cells). This discovery may help treat numerous patients diagnosed with fatal diseases in the future. Also, these cells can help test experimental drugs, help doctors understand birth defects, and provide essential clues about how the tissues of the body develop and how they take hold (Stem Cells). Now, why the controversy? Embryonic stem cells are obtained from embryos and once they...
