What can stem cells do for you?

Stem cells are so diverse and can be used for so many things. Most people know about how it can potentially help with cancer. This is true. Cancer could be lessened maybe possibly even cured. All they have to do is make the cells form into whatever organ or tissue that you need and your cured. everything in your body is ok and put back to normal. Most people a;so know that it can help change or cure certain uncurable dieseases. Dieseases occur when there are mutations in the body or cells dna. brand new cells can be made into new cells that have no mutations or problems in it. Then everything is good again. i think that one day, they can be used to make whole body parts. For people that lose limbs are that need organs and body parts. This will be helpful because then everyone can fit into this society as being "normal". Also people that become paralyzed can become un paralyzed. So many medical marvels could come out of these little cells. I do believe that clones of people would be taking it too far. we dont need that? What good could possibly come from that?
