Some cells pause -- or are intentionally made to pause -- in the process. When the cell resumes division after such a pause, a displaced nucleus -- an essential part of cell survival -- can become caught in the fissure, splitting violently and killing both cells. But that is not always the case; some mutant cells can recover by pushing their nucleus to safety. Researchers from Hiroshima University in Japan are starting to understand how in the first step toward potential cell death rescue applications.
