For years we have been told that one reason ES cells are superior to adult stem cells is that they are “immortal,” that is, they can remain viable in culture indefinitely. Several previous studies cast doubts on this assertion, and now another one seems to have put it into its grave by demonstrating that over time ES cells develop mutations that could cause cancer. Ooops.
You would think this would give the media pause over the other hyped assertions made by ESCR proponents. But nooo. The collapse of this supposedly superior attribute is merely spun as a reason to spend even more money on the research.
I was going to Blog this story myself, but Michael Fumento beat me to it, and, as usual, his thoughts are right on the money. Check it out.
