What Are the Benefits of Stem Cell Research?

I have heard a lot of people saying how stem cell research is wrong because it could lead people to do unethical things. However, I haven’t heard enough about the benefits of stem cell research. I do know they suspect stem cells can help to cure people with certain diseases, so I would love to learn more about this. I think that it is really important to try to cure some of these diseases that are causing so many people to suffer and die before their time. I am especially hoping they can cure the diseases that affect children as well as adults.
