Stanford researcher identifies unusual ‘altruistic’ stem cell behavior with possible link to cancer

When most groups of mammalian cells are faced with a shortage of nutrients or oxygen, the phrase “every man for himself” is more apt than “all for one, one for all.” Unlike colonies of bacteria, which often cooperate to thrive as a group, mammalian cells have never been observed to help one another out. But a new study led by a researcher at the Stanford University School of Medicine has shown that certain human embryonic stem cells, in times of stress, produce molecules that not only benefit themselves, but also help nearby cells survive.
