Dormancy of stem cells enables them to remain viable…many days post mortem
06/12/2012 - Researchers from the Institut Pasteur, the Université de Versailles Saint-Quentin-en-Yvelines, the Paris Public Hospital Network (AP-HP), and the CNRS have shown for the first time in humans and mice, the capacity of stem cells to adopt a dormant state when their environment becomes hostile, including several days after death.

After isolation, they can then be used to repair damaged organs or tissues. This discovery could lead to new therapeutic avenues for treating numerous diseases. The study is being published today in the journal Nature communications.
