Part of the reason, say researchers at Stanford University School of Medicine, is the presence of a protective pathway meant to shield normal stem cells from DNA damage. When the researchers blocked this pathway, the cells became more susceptible to radiation. http://www.physorg.com/news152977118.html Medicine & Health Wed, 04 Feb 2009 13:39:16 EST news152977118
