DNA's Genetic Mosaic Revealed By Skin Cells

There is an interesting report at http://www.medicalnewstoday.com/releases/252994.php

Here is just part of it....
"The prevailing wisdom has been that every cell in the body contains identical DNA. However, a new study of stem cells derived from the skin has found that genetic variations are widespread in the body's tissues, a finding with profound implications for genetic screening, according to Yale School of Medicine researchers."

Lately  there have been very interesting advances with Stem Cells. We have the future to look forward to.
