      It’s really difficult to say, there are about 30 trillion cells in the human body, but really we don’t know what proportion of these are stem cells. My guess is less than 0.001%, which is still around 300 million cells.

      But that is an estimate, I’d love to be able to give a more accurate answer but we really don’t know I’m afraid!
