One hallmark of most cancer cells is that they have the incorrect number of chromosomes, a state called aneuploidy. Now, researchers at the University of Virginia Health System, writing in a recent issue of the journal Current Biology, think they know how cells protect themselves from aneuploidy when they divide in a process known as mitosis. “During mitosis, the cell divides replicated chromosomes to two daughter cells. We are studying a mitotic system that ensures that each cell receives the right number of chromosomes,” said article co-author Todd Stukenberg, assistant professor of biochemistry and molecular genetics at U.Va.
