The most controversial type of stem-cell research comes from embryonic stem cells, which is human fetus approx. 50-150 cells in size. It is often a moral question as to whether or not experimenting on these fetuses should be allowed. Throughout the years the laws have changed on its allowance, sometimes being legal and other times illegal. Currently embryonic stem cell research is legal. Scientists say stem cell research may cure a number of ailments including Spinal Cord Injury, Diabetes, Parkinson's, Alzheimer's and others.1
The benefits of embryonic stem-cell research outweigh the negatives. The embryonic stem cells are a small group of cells and is no different than experimenting on a tiny piece of skin not even visible to the human eye.
The embryonic cells are humans in their earliest stages of life. To experiment with these stem-cells is experimenting with humans. Cloning is not acceptable either as it is simply creating life to destroy life.
