The Fear of Stem Cells

The discovery of stem cells is one of those discoveries almost like DNA that forces us to think differently about what we're made of and how our bodies work. We all have a billion stem cells in our bodies as adults. And I can tell you that for most of us as we age, we wish we had more of them, not fewer. As we age, the number of stem cells we have goes down and the function of the ones that we have decreases.
