Why not just study adult stem cells?
Adult stem cells have some advantages. When they come from your own body, your immune system will probably not try to reject them. And adult stem cells aren’t controversial. But there are three main disadvantages to using adult stem cells: • Adult stem cells aren’t able to form all types of cells, so their use may be limited. • Adult stem cells are rare among the body’s billions of cells, so they’re hard to find. • Adult stem cells take a long time to grow.
