A team of Canadian scientists identified 1,155 genes under the control of a single gene called Oct4, the master regulator of the stem cell state. Researchers developed a comprehensive definition of stem cells on a molecular basis such that stem cells keep their DNA packed in a flexible format, keep cell division tightly controlled, prevent signals that trigger death and repair DNA. “You could call this a 'theory-of-everything' for stem cells,” said Michael Rudnicki, senior scientist at the Ottawa Health Research Institute.
