Adult Stem Cells May Have Smarts To Guard Against Cancer, Stanford Researchers Find

The findings, from the lab of Thomas Rando, MD, PhD, associate professor of neurology and neurological sciences, suggest stem cells are careful when they undergo cell division so that random mutations in their chromosomes are not passed on to the next generation of stem cells. The results support a much-debated hypothesis proposed in 1975 by Oxford University geneticist John Cairns, PhD. Although other groups have uncovered hints that Cairns was right, Rando’s findings are the most detailed to date.

The results are published in the April 17 issue of the Public Library of Science-Biology.
Rando said no other work he’s done has created as much excitement among his colleagues in the stem cell field. “The lesson from this is that when something seems strange, don’t ignore it. Sometimes what puzzles you turns out to be the most interesting,” he said.
