What Breaks a Cell’s Ribs Can Make It Stronger
The process of cell division exerts powerful forces on the cell's molecular machines, and researchers have been studying how these machines manage the strain. The mitotic spindle, a dynamic rib cage made of microtubules, plays a crucial role in cell division, and its ability to withstand forces without breaking apart has been a scientific mystery. Recent experiments have shown that the spindle has a self-repair mechanism that enables it to stabilize itself under force and avoid disintegrating.
