Stem cells, cancer and “bad luck”

Bilbao, Spain - January 16, 2015

Just a few weeks ago a paper by Tomasetti and Vogelstein describing a mathematical model that correlates cancer incidence with the number of stem cell divisions in a plethora of human tissues was published in Science. This parameter is related to the cell replication activity of a particular tissue, ie, the cell turnover rate in that tissue, as some tissues renew their cells more slowly than others (compare brain tissue to intestinal epithelium). For about 2/3 of the tumors explored...
