Cells re-energize to come back from the brink of death

The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators at St. Jude Children's Research Hospital insights into a key strategy cancer cells use to survive and thrive. The finding of...

In this way, he said, physicians might avoid the usual pitfall involved in transplanting cells or organs from other people — organ rejection, which requires organ recipients to take immune-suppressing drugs for the rest of their lives. Huge numbers of stem cells are thought to be required to...
